FAQ

Those who are looking for an answer to the question «Why calculate ash content in chemicals?» often ask the following questions:

### 📋 How to calculate nco content?

It is determined by dividing %NCO into 4,200. For example, a typical polyisocyanate with a %NCO content of 23 would have an equivalent weight of 182. The mix ratio is the number of equivalents of NCO divided by the equivalents of OH.

### 📋 How do you calculate binder content?

Asphalt binder content is calculated as the difference between the initial mass of the HMA and the mass of the residual aggregate, correction factor, and moisture content. The asphalt binder content is expressed as percent of moisture-free mix mass. Two methods, A and B, are presented.

### 📋 How do we calculate blood alcohol content?

To calculate BAC, the amount of alcohol in the bloodstream is measured in milligrams (mg) of alcohol per 100 milliliters (ml) of blood. It is usually expressed as a decimal such as 0.08 or 0.15. For example, a BAC of 0.10% means that an individual's blood supply contains one part alcohol for every 1,000 parts blood.

### How to calculate the moisture content of water?

• The following formula can be used to calculate moisture content. MC = (w – d) / w * 100. Where MC is the moisture content (%) w is the weight while wet; d is the weight while dry; Moisture Content Definition. Moisture content is defined as the percentage of the weight of a saturated object that is associated with water.

### How to calculate total phenolic content from absorbance?

Gallic acid is used as a standard compound and the total phenols were expressed as mg/g gallic acid equivalent using the standard curve equation: y = 0.0061x + 0.0396, R2 = 0.9991, Where y is absorbance at 760 nm and x is total phenolic content in the different extracts.

### Do you need specific gravity to calculate alcohol content?

• Also, you’ll need the final specific gravity taken once your wine has finished fermenting and is stable. Just plug in both values and press calculate. This is about as accurate as you can get with the equipment and methods available to amateur wine makers.

### How can you calculate organic matter content in soil?

The amount of oxidizable organic carbon and the degree of weight loss from sustained temperatures at 680 degrees Fahrenheit (360 degrees Celsius) are ways to calculate the organic matter content in soil. The first-mentioned measure is the Walkley-Black method that employs hazardous chromic acid in soils whose organic matter measures at less than two percent. The second-mentioned measure is the Weight Loss on Ignition method whose weight loss gets correlated with oxidizable organic carbon in soils whose organic matter measures at more than six percent.

### How do you calculate the alcohol content of beer?

• The most commonly used formula to calculate Blood Alcohol Content is: %BAC = (A x 5.14/W x r) – .015 x H, where. “A” is the number of liquid ounces of alcohol consumed. For example, the standard 5% beer would be .60 (12 x 0.05)

### How to calculate the heat content of a substance?

• The sum of these energies in one mole of a substance is called the Molar Enthalpy ( H ) or The Heat Content of the Substance . It is the sum of the stored energies in one mole of a substance , The molar enthalpy of NO2 gas equals 33.58 kJ/mol means that the sum of the stored energies in 46 g ( 1 mol ) of NO2 gas equals 33.58 kJ .

### How to calculate your estimated blood alcohol content bac?

• Calculate Blood Alcohol Content The most commonly used formula to calculate Blood Alcohol Content is: %BAC = (A x 5.14/W x r) –.015 x H, where “A” is the number of liquid ounces of alcohol consumed.

### Is there a way to calculate blood alcohol content?

• Use our calculator to estimate, but don't forget that everyone metabolizes alcohol (beer, wine, liquor) differently. Our calculator can give you an approximate BAC level, but do not rely upon it to determine if you're fit to drive or work. The BAC calculator is meant for educational purposes only.

### How do you calculate moisture content in existing concrete floors?

There are several test devised, pertaining to moisture content in concrete! Everything from vapor emissions to relative humidity. By Far the most reliable is ASTM 2170 that measures the relative humidity inside the concrete. Unusual question for a lay person, since most people don't even consider concrete is a giant sponge! Don't fall for ASTM 1869 as a test method --- Very cheap, but not worth much. If someone shows up with a surface moisture meter for testing --- Show him the Door!

### How to calculate the moisture content of a soil sample?

• To arrive at the total of moisture in soil, use the following equation where soil moisture is solution C. { (A-B)/A}*100=C. In other words, subtract solution B from solution A and divide the total by solution A. Multiply the answer by 100. The total that you receive is the moisture content of the sample.
