chemistry find the missing part of the equation

Question

(34. g/mL) • ____ = ? g/L

Answer 1

Hi!

So the main clue here is the units. We are looking for something that, when multiplied by g/ml, gives us g/L, so we want a conversion factor that changes ml to L. Since 1000 ml are in one L, we would multiply by 1000 ml/L to give us 34000 g/L. We know this works because 1) g/ml * ml/L = g/L and 2) the answer is larger, since the number of grams of the substance in a ml should be smaller than the number of grams in a liter.
