Question

Write a formula showing the dependence of the mass of a piece of cork on its volume, if the density of cork is 0.18g/cm3. Using the formula, find the mass of a piece of cork with a volume of 240 cm3

Answer 1

Answer:

43.2 grams.

Step-by-step explanation:

We are asked to write a formula showing the dependence of the mass of a piece of cork on its volume.

We will use density formula to solve our given problem.

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

$\text{Density}\times {\text{Volume}}=\text{Mass}$

$\text{Mass}=\frac{\text{ 0.18 g}}{\text{cm}^3}\times\text{240 cm}^3$

$\text{Mass}=\text{ 0.18 g}\times 240$

$\text{Mass}=\text{43.2 g}$

Therefore, the mass of piece of cork is 43.2 grams.

Answer 2

Mass: density × volume
so, 0.18 × 240 = 43.2g
