Question

Ethanol is a common laboratory solvent and has a density of 0.7890.789 g/mL. What is the mass, in grams, of 129129 mL of ethanol

Answer 1

101.78 g

Step-by-step explanation:

We know that density is given by; mass/volume

Mass = ?

Density = 0.789 g/ml

Volume = 129 ml

Mass = volume × density

Mass= 129 ml × 0.789 g/ml

Mass= 101.78 g
