Answer:
95.49 g
Explanation:
D = m/v
Looking for mass so isolate m to form equation format
D × V = m
Plug in numbers
.7892g/mL × 121.0 mL = 95.4932 g
Only g and not g/mL because the mL cancels each other out. It's easier to see if you rewrite it on paper.
Round to sig figs
Both original numbers hold 4 sig figs
95.49 g
