What is the mass of a sample that has a density of 0.921 g/mL, and a volume of 1.21mL?

To find the mass of the sample, we can use the formula:

mass = density x volume

Substituting the given values:

mass = 0.921 g/mL x 1.21 mL

mass ≈ 1.114 g

Therefore, the mass of the sample is approximately 1.114 grams.
