How do you determine the number of grams in 2.5 moles of NaCl?

Calculate the mass of 2.5 moles of NaCl. Determine the mass in grams of 0.500 moles of Ca(OH)2.

1. m(NaCl) = M×n. …
2. m((Ca(OH)2) = 0.500×74 = 37 g.
3. m(NH3) = 0.010×17 = 0.17 g.
4. m(CO2) = 3.0×44 = 132 g.
5. n(HgS) = m/M. …
6. n(H2O) = 27.0/18 = 1.5 mole.

How do you find moles of NaCl?

One mole of sodium (Na) is 22.99 g, and 1 mole of chlorine is 35.45 g. For sodium chloride (NaCl) they are in a ratio of 1:1 so the molar mass of NaCl is 22.99 + 35.45 = 58.44 g/mol.

How many atoms are in 3.75 moles?

What is the mass of 1 mole?

The molar mass of some substance is the mass in grams of one mole of that substance. This mass is given by the atomic weight of the chemical unit that makes up that substance in atomic mass units (amu). For example, gold has an atomic weight of 196.967 amu, so one mole of gold has a mass of 196.967 grams.
