Convert the following measurement: 37.5 g/mL to kg/L?

Question

I know you need to use multiple conversion factors, but cant seem to figure this out.

Taken from Glencoe Science Honors Chemistry book

Answer 1

Well, first you realize that there are 1,000 gm to 1 kg, and that there are 1000 ml to 1 lL. So, multiply 37.5 g/ml * (1 kg/1000g) * (1000 ml/1L). Units reduce to kg/L and 1/1000 * 1000/1 reduces to multiplying by 1.

So, the answer is 37.5 kg/L

Answer 2

its actually 37.5 kg/L

1000g = 1 kg
1000 mL = 1 L

37.5 g/mL x 1 kg / 1000 g x 1000mL / 1 L = 37.5 kg/L

Answer 3

37.5 g/mL x 1 kg/1000 g x 1000 mL/L = 37.5 kg/L

Answer 4

37.5

Answer 5

37.5g/mlx1000ml/1Lx1kg/1000g=
37.5kg/L !!!
