Question

What is the mass, in grams, of 28.64 ml of acetone?

Answer 1

Mass of an object is calculated by multiplying its density by volume. It is the amount of matter in a object or a body.
Acetone has a density of 0.79 g/cm³ or 0.79 g/ml
Therefore, mass = 28.64 × 0.79 =22.626 g
Hence. the mass of acetone is 22.626 g

Answer 2

Answer: The mass of acetone is 22.50 grams.

Step-by-step explanation:

Density : It is defined as the mass contained per unit volume.

To calculate mass of a substance, we use the equation:

`\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}`

We are given:

Density of acetone =
`0.7857g/mL`

Volume of acetone = 28.64 mL

Putting values in above equation, we get:

`0.7857g/mL=\frac{\text{Mass of acetone}}{28.64cm^3}\\\\\text{Mass of acetone}=22.50g`

Hence, the mass of acetone is 22.50 grams.
