Answer:
The answer is
390 g
Step-by-step explanation:
The mass of a substance given the density and volume can be found by using the formula
mass = Density × volume
From the question
Density = 1.30 g/cm³
volume = 300 mL
Substitute the values into the above formula and solve
That's
mass = 1.3 × 300
We have the final answer as
390 g
