Question

If a substance has a density of 1.345g / mL , how many grams would the substance weigh if the sample has a volume of 22.1 ml?

Answer 1

To find the mass of a substance based on its density and volume, multiply the density (1.345 g/mL) by the volume (22.1 mL). The mass is then 29.7255 grams, which is usually rounded to 29.73 grams to match the significant figures of the given values.

Step-by-step explanation:

If a substance has a density of 1.345g/mL, and you have a volume of 22.1 mL, you can calculate the mass by multiplying the density by the volume.

The formula to use is:

Mass = Density × Volume

Using the given values:

Mass = 1.345 g/mL × 22.1 mL

Therefore, the mass of the substance is:

Mass = 29.7255 grams,

which will typically be rounded to reflect the correct number of significant figures from the given values. In this case, you would round to 29.73 grams as the volume has three significant figures.

Answer 2

Mass of substance = 29.7245 gram

Step-by-step explanation:

Given:

Density of substance = 1.345 g / ml

Volume of substance = 22.1 ml

Find:

Mass of substance

Computation:

Mass = Density x Volume

Mass of substance = Density of substance x Volume of substance

Mass of substance = 1.345 x 22.1

Mass of substance = 29.7245 gram
