Question

Calculate the mass of a liquid with a density of .7892 g/mL and a volume of 121.0 mL.

Answer 1

Answer:

95.49 g

Step-by-step 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
