Question

What is the volume of 700.0 g of ether if the density of ether is 0.70 g/mL?

How would I solve this? I always get confused with problems like this. Please help and explain!

Answer 1

you just need to remember the relation between mass, volume and density

density = mass/volume

Answer 2

So would I go 0.70 g/mL = 700.0g/volume mL ?

Answer 3

yes 0.70 = 700 / V where V is in mL

Answer 4

Then do the mL cancel out or do I just divide the density with the mass?

Answer 5

cross multiply:-
0.70V = 700
divide both sides by 0.70
V = 700 / 0.70

Answer 6

so it would be 1.000?

Answer 7

yes

Answer 8

So that would be the volume of ether in the problem?

Answer 9

yes 1,000 mL

Answer 10
