B mol/g
C L/ g
D mol/L

Answer 1

mol/L

Step-by-step explanation:

took the apex test :)

Answer 2

D mol/L

Explanation:

You want to convert g/mol to g/L.

You need a conversion factor with mol on top (to cancel the mol in your measurement) and the desired unit (L) on the bottom.

The conversion factor must have the units mol/L.

===============

Example:

The molar mass of water is 18.02 g/mol and there are 55.49 mol in 1 L

(1000 g) of water.

`\frac{\text{18.02 g }}{\text{ 1 mol}} * \frac{ \text{55.49 mol}}{\text{1 L}} = \text{1000 g/L}`

We know that the mass of 1 L of water is 1000 g, so the conversion factor is correct.
