Question

What is the mass in grams of 1.000 mol NaCl?

Answer 1

Adding up these two quantities (23.00 + 35.45) gives us the molarmass of NaCl, which is 58.45grams per one mole. Therefore, if we have 1.000 mol of NaCl, we have exactly 58.45 grams of NaCl, which is the molar mass.

Answer 2

The mass of given amount of NaCl is 58.5 g

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Moles of NaCl = 1.000 moles

Molar mass of NaCl = 58.5 g/mol

Putting values in above equation, we get:

$1.000mol=\frac{\text{Mass of NaCl}}{58.5g/mol}\\\\\text{Mass of NaCl}=(1.000mol\times 58.5g/mol}=58.5g$
