Answer:
The answer is
555.94g
Explanation:
To find the mass of a substance given it's density and volume we use the formula
<h2>
</h2>
Making mass the subject we have
mass = Density × volume
From the question
Density = 7.7 g/cm³
Volume = 72.2 cm³
Substitute the values into the above formula
That's
mass = 7.7 g/cm³ × 72.2 cm³
We have the final answer as
<h3>mass = 555.94g</h3>
