Question

How many grams of NaCl are in 0.78 moles of NaCl? *

Answer 1

The molar mass of NaCl is 23 + 35.5 = 58.5 g/mol, so the mass of the sample ia 0.78 × 58.5 = 45.63 g.

Answer 2

There is 45.58 grams of NaCl  in 0.78 moles

What are moles ?

Moles is a measurement unit in Chemistry for measuring large number of molecules and atoms.

1 mole is equal to 6.022 * 10²³ atoms

It is calculated by dividing mass of the molecule/compound by Molar mass of the substance.

Mass of 1 mole of a substance = Molar mass of the substance

0.78 moles of NaCl = ? grams

1 mole of NaCl means 58.44 grams.

0.78 moles  = 0.78 * 58.44

0.78 moles of NaCl = 45.58 grams of NaCl

Therefore there is 45.58 grams of NaCl  in 0.78 moles.
