Answer:

9.98 g.

Step-by-step 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!
