Answer 1

Answer:

103.3 g

Explanation:

Data Given:

Volume of carbon tetrachloride (v) = 65.0 mL

Density of carbon tetrachloride (d) = 1.59 g/cm³

Solution:

Convert volume of carbon tetrachloride from ml to cm³

1 ml = 1 cm³

so,

65.0 mL = 65.0 cm³

Formula used to calculated mass of carbon tetrachloride should be taken for experiment.

                   d = m/v

Rearrange the above equation:

                   m = d x v . . . . . . .(1)

Put values in equation 1

                   m = 1.59 g/cm³ x 65.0 cm³

                   m = 103.3 g
