Answer 2

Answer: The mass of sodium sulfate is 1420 grams.

Explanation:

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

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

For Sodium sulfate:

Given mass = ? g

Number of moles = 10 moles

Molar mass of $Na_2SO_4$ = $[(2\times 23)+32+(4\times 16)]=142g/mol$

Putting values in above equation, we get:

$10mol=\frac{\text{Mass of sodium sulfate}}{142g/mol}\\\\\text{Mass of sodium sulfate}=1420g$

Hence, the mass of sodium sulfate is 1420 grams.
