Answer:
The answer is
0.075 kg
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 = 762 kg/m³
We must first convert the volume from cm³ to m³
[tex]1 \: {cm}^{3} = 1 \times {10}^{ - 6} {m}^{3} [/tex]
So 99 cm³ will be
[tex]9.9 \times {10 }^{ - 5} \: \: {m}^{3} [/tex]
So the mass of the material is
[tex]mass = 762 \times 9.9 \times {10}^{ - 5} \\ = 0.075438[/tex]
We have the final answer as
0.075 kg
Hope this helps you
