Answer:
mass = 157.8 g
Step-by-step explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question
Density = 0.789 g/mL
volume = 200 mL
Substitute the values into the above formula and solve for the mass
That's
mass = 0.789 × 200
We have the final answer as
mass = 157.8 g
