Question

What is the mass of 53 mL of ethyl alcohol, which has a density of 0.79 g/mL? M 53 g B) 41.9 g C) 67 g D) 67.1 g

Answer 1

Answer: 41.9 g

Step-by-step explanation:

Given:

volume= 53ml

density=0.79 g/mL

mass=?

To find the mass, we multiply density by volume. So,

`\begin{gathered} \text{mass = density x volume} \\ =((0.79g)/(ml))(53ml) \\ \text{Calculate} \\ =41.9\text{ g} \end{gathered}`

Therefore, the mass is 41.9 g.
