Question

A student needs to use 0.575 moles of sodium chloride in an experiment. How many grams should he mass out?

Answer 1

The molecular weight of NaCl is 58.44 g/mol.

0.575 mol * 58.44 g/mol = 33.6 grams of NaCl

Answer 2

33.6 g

Step-by-step explanation:

Step 1. Calculate the molar mass of NaCl

Na = 22.99

Cl = 35.45

Total = 58.44 g/mol

Step 2. Calculate the mass of NaCl

Mass of CO₂ = 0.575 mol NaCl × (58.44 g NaCl/1 mol NaCl₂)

Mass of CO₂ = 33.6 g CO₂
