Question

Calculate the mass of 12 mL of a substance whose density is 1.1 g/mL. Express your answer in grams using the correct number of significant figures. Do not enter your answer using scientific notation.

Answer 1

To find the mass of the substance, multiply the given density (1.1 g/mL) by the given volume (12 mL) to get a mass of 13.2 grams, with the answer rounded to two significant figures.

Step-by-step explanation:

To calculate the mass of a substance, you can use the formula mass = density × volume. Given a density of 1.1 g/mL and a volume of 12 mL, you simply multiply these two values together to find the mass.

Mass = 1.1 g/mL × 12 mL = 13.2 g

The density has two significant figures and the volume has two as well, so our final answer will be reported with two significant figures, hence 13.2 grams is the mass.

Answer 2

Step-by-step explanation:

It is known that density is the amount of mass which is present in a liter of substance.

Mathematically, Density =
`(mass)/(volume)`

It is given that volume is 12 mL and density is 1.1 g/ml. Hence, the density will be calculated as follows.

Density =
`(mass)/(volume)`

1.1 g/ml =
`(mass)/(12 ml)`

mass = 13.2 g

Thus, we can conclude that mass of the given substance is 13.2 g.
