Material of density of 762 kg/m3 occupies a container

konstantin123 [22]

Answer:

The answer is

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

density = 762 kg/m³

We must first convert the volume from cm³ to m³

$1 \: {cm}^{3} = 1 \times {10}^{ - 6} {m}^{3}$

So 99 cm³ will be

$9.9 \times {10 }^{ - 5} \: \: {m}^{3}$

So the mass of the material is

$mass = 762 \times 9.9 \times {10}^{ - 5} \\ = 0.075438$

We have the final answer as

Hope this helps you
