How do you find volume from density? Ex. ethanol is 0.7983 g/ml. What is the volume of 4.5 kg of ethanol?

Question

Ex. ethanol is 0.7983 g/ml. What is the volume of 4.5 kg of ethanol?

Answer 1

4500g (1mL/0.7983g)

g will cancel

5636.98mL

Answer 2

plug the values into the problem

d=m/v

.7983=4500/v  then solve for v

v= 4500/.7983

good luck

Answer 3

grams / grams per mL = mL

4500 g / 0.7983 g/mL = 5637

2 significant digits to 5600 mL

Answer 4

Density is mass over volume, so in order to find volume by cancelling terms, you need to multiply the reciprocal of the density by the mass, e.g., 4.5 kg EtOH x 1 ml/0.7983g EtOH x 1000 g/1 kg = 5600 ml EtOH = 5.6 l EtOH.
