Ethanol is a common laboratory solvent and has a density of 0.789 g/mL. What is the mass, in grams, of 133 mL of ethanol?

Respuesta :

Given:

[tex]V = \text{133 mL}[/tex]

[tex]\rho = \text{0.789 g/mL}[/tex]

Required:

[tex]m[/tex]

Solution:

[tex]\rho = \frac{m}{V}[/tex]

[tex]m = \rho V[/tex]

[tex]m = (\text{0.789 g/mL})(\text{133 mL})[/tex]

[tex]\boxed{m = \text{105 g}}[/tex]
