\({\%~of~an~element} = \frac{mass~of~an~element~in~the~compound}{relative~formula~mass~M_r} \times 100\) There are six atoms of hydrogen in the compound, so the mass ...

Body Mass Index, or BMI, is an index used to determine healthy body weight. But, calculating BMI involves a complex formula, and then charts or online calculators are needed to convert the BMI ...

I've written about numerical calculations before, but perhaps they weren't too inspiring. What are numerical calculations? Here is my own definition. Numerical Calculations (numerical methods, ...

To calculate the mass of a higher number of moles, or even calculate the number of moles in a certain mass, a formula triangle can be used. Using the formula triangle is straightforward. Simply cover ...

The current BMI calculation gives tall people the short end of the stick, an Oxford mathematician says. Body mass index, or BMI, has long been used as the quickest measure of whether a person’s weight ...

BMI stands for Body Mass Index and is a useful measurement for most people over 18. It is a measurement derived from your weight and height that estimates your body composition. It tells you whether ...

The present application note explains how to calculate the molar mass Mw based on the Zero-Shear Viscosity value measured by a Frequency Sweep. The Zero-Shear Viscosity can be evaluated by applying ...

Everyone knows Luke Skywalker travels to Dagobah to learn the ways of The Force (like his father before him). He trains with Jedi master Yoda. Perhaps you recall the scene where Luke does a one-armed ...
