Chemistry is full of many different confusing conversions. These conversions are important because they ultimately allow us to discover how a particular atom or molecule will interact with other atoms and molecules. Central to chemical conversions is the conversion of grams to moles, and vice versa....

TL;DR (Too Long; Didn't Read) The number of moles of solute = mass of solute ÷ molar mass of solute, where mass is measured in grams and molar mass (defined as the mass of one mole of a substance in grams) is measured in g/mol.Concept...
This is consistent with the concept of mole as a measure of a count. What makes the number of moles of a sample of barium chromate different is that it connects to a specific mass of the compound according to the molar mass of the compound....
Using Molar Mass Now, you can tackle the question at the beginning of the article. Say you need to make 1 L of a 1M NaCl solution. How do you know how much salt to weight out? First, you will need to find the number of moles you need for this solution. To do this, you will ...
Moles to Grams Example Problem Sometimes you're given a value inmolesand need to convert it to grams. To do this, first calculate the molar mass of a sample. Then, multiply it by the number of moles to get an answer in grams:
