To convert milliliters to liter, multiply a converson factor of [tex] \frac{1000ml}{L} [/tex] which means that for every 1 Liter, there is exactly 1000 mL. Converting 0.15 g/mL, multiply the conversion factor to cancel out the unit of milliliters, as shown in the solution below:
[tex]0.15 \frac{g}{mL} ( \frac{1000 mL}{L} ) = 150 g/L[/tex]
The answer is 150 g/L
