Question

The density of water may be taken to be 0.9980 g/mL at 21oC. Considering the volume of water that you used to prepare the the sodium chloride solution, calculate the mass in grams of water. Enter the mass to the nearest thousandth of a gram.

Answer 1

Answer:

9.98 g.

Explanation:

Hello!

In this case, given the information found on the problem, we can see that the taken volume of water was 10 mL, and considering the formula of density:

$d=m/V$

The mass would be computed as follows:

$m=d*V\\\\m=0.998g/mL*10mL\\\\m=9.98 g$

Thus, the nearest thousandth of a gram would also be 9.98 g.

Best regards!
