Answer 1

32 grams

Step-by-step explanation:

To find the mass of the object, you need to multiply the given volume by the denisty. The denisty ratio compares the mass of an object per every 1 mL. It is important to arrange the denisty ratio in a way that allows for the cancellation of units (mL should be in the denominator). The final answer should have 2 sig figs.

Denisty = 1.35 g/mL

24 mL 1.35 g
---------------- x ----------------- = 32.4 g = 32 g (correct sig figs)
1 mL
