Find the density of a substance that’s had a volume of 24.7mL and a mass of 49.1g. Give the answer with two decimals.

1.99 g/mL

Explanation:

Use the formula d = m/v, where m is the mass and v is the volume.

Plug in the values:

d = 49.1/24.7

d = 1.99 g/mL

About 1.99 g/mL

Explanation:

The density of a substance can be found using the following formula:

d= m/v

where m is the mass and v is the volume.

The mass of this substance is 49.1 grams and the volume is 24.7 milliliters.

m= 49.1 g

v= 24.7 mL

Substitute these values into the formula.

d= 49.1 g / 24.7 mL

Divide 49.1 g by 24.7 mL

d= 1.98785425 g/mL

We are asked to round to two decimal places, or the hundredth place. The 8 in the thousandth place tells us to round the 8 to a 9 in the hundredth place.

d ≈ 1.99 g/mL

The density of the this substance is approximately 1.99 grams per milliliter.
