Question

30.0 g of each of the following acids are needed. Find the volume of each that must be measured out in a
graduated cylinder.
6 hydrochloric acid (HCI), density = 1.164 g/mL
7 sulfuric acid (H2SO4), density = 1.834 g/mL
8 nitric acid (HNO3), density = 1.251 g/mL

Answer 1

Answer:

6. 25.8 mL.

7. 16.4 mL.

8. 24.0 mL.

Explanation:

6. Determination of the volume of HCl.

Mass = 30 g

Density = 1.164 g/mL

Volume =..?

Density = mass /volume

1.164 = 30 / volume

Cross multiply

1.164 × volume = 30

Divide both side by 1.164

Volume = 30 / 1.164

Volume = 25.8 mL

7. Determination of the volume of H2SO4.

Mass = 30 g

Density = 1.834 g/mL

Volume =..?

Density = mass /volume

1.834 = 30 / volume

Cross multiply

1.834 × volume = 30

Divide both side by 1.834

Volume = 30 / 1.834

Volume = 16.4 mL

8. Determination of the volume of HNO3.

Mass = 30 g

Density = 1.251 g/mL

Volume =..?

Density = mass /volume

1.251 = 30 / volume

Cross multiply

1.251 × volume = 30

Divide both side by 1.251

Volume = 30 / 1.251

Volume = 24.0 mL
