Answer: The mass of the sample is 90 grams.
Explanation:
To calculate the mass of sample, we use the equation:
[tex]\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}[/tex]
Volume of sample = 120 mL
Density of sample = 0.75 g/mL
Putting values in above equation, we get:
[tex]0.75g/mL=\frac{\text{Mass of sample}}{120mL}\\\\\text{Mass of sample}=90g[/tex]
Hence, the mass of the sample is 90 grams.
The sample with a volume of 120 mL and a density of 0.75 g/mL has a mass of 90 g.
Density (ρ) is an intrinsic property of matter. It is the quotient between the mass (m) and the volume (V). We can find the mass of a sample with a volume of 120 mL and a density of 0.75 g/mL, using the following expression.
[tex]\rho = \frac{m}{V} \\m = \rho \times V = \frac{0.75g}{mL} \times 120 mL = 90 g[/tex]
The sample with a volume of 120 mL and a density of 0.75 g/mL has a mass of 90 g.
