Answer: The density of a substance is 2 g/mL

Explanation:

To calculate the mass of solution, we use the equation:

[tex]\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}[/tex]

We are given:

Mass of a substance = 40 g

Volume of a substance = 20 mL

Putting values in above equation, we get:

[tex]\text{Density of a substance}=\frac{40g}{20mL}=2g/mL[/tex]

Hence, the density of a substance is 2 g/mL

The density of a substance that has a mass of 40g and a volume of 20mL is 2g/mL.

HOW TO CALCULATE DENSITY:

  • The density of a substance can be calculated by dividing the mass of the substance by its volume. That is;

  • Density (g/mL) = mass(g) ÷ volume (mL)

  • According to this question, the mass of substance is given as 40g and a volume of 20mL. The density is calculated as follows:

  • Density = 40g ÷ 20mL

  • Density = 2g/mL

  • Therefore, the density of a substance that has a mass of 40g and a volume of 20mL is 2g/mL.
