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 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.
