Molar mass has the units of grams/mole. Molar mass serves as a conversion factor between numbers of moles and mass.

Molar mass has the units of grams/mole. Molar mass serves as a conversion factor between numbers of moles and mass. If you know how many moles you have, you can calculate their mass; if you know the mass of a sample, you can calculate the number of moles. What is the mass of 0.2 moles of hydrazine? If you had 8 grams of N2H4, how many moles of N2H4 molecules would there be? How many individual molecules of N2H4 is this? The coefficients in a balanced chemical equation tell how many molecules, and thus how many moles, of each reactant are needed and how many molecules, and thus moles, of each product are formed. This number of N2 molecules The coefficients can be put in the form of mole ratios, which act as conversion factors when setting up factor-label calculations. How many moles of ammonia (NH3) could be formed from 0.6 moles of N2? Mass to mass conversions are frequently needed, but cannot be carried out directly. STEP 1: Write the balanced chemical equation. How many g
