Question

A graduated cylinder is filled to 20mL. A piece of silver is added to the cylinder and the volume of water increases to

30mL. The density of silver is 10.49 g/mL, what is the mass of this piece of silver?

Answer 1

104.9 g

Step-by-step explanation:

If you add a piece of silver to water which increases the volume of the water from 20 mL to 30 mL, according to water displacement, the piece of silver must be 10 mL (30 mL - 20 mL = 10 mL).

You can find the mass by multiplying the volume of silver by the density. The denisty exists as a ratio comparing the mass (g) of silver per every 1 mL. It is important to arrange the ratio in a way that allows for the cancellation of units (mL should be in the denominator).

10 mL 10.49 g
-------------- x ----------------- = 104.9 g
1 mL
