mass = volume x density
mass = 750 mL x 0.930 = ??grams, then convert to kg.
what is the mass in kilograms of 750 mL of a substance that has a density of 0.930 g/mL?
4 answers
With these types of calculations it is very useful to include units. This tends to stop quite a few simple errors.
So here
mass = 750 mL x 0.930 g/mL
we can see that ml will cancel and we are left with g
which we then convert to kg
So here
mass = 750 mL x 0.930 g/mL

answer is incorrect because:
it is numerically incorrect
it is missing the unit
it is missing the leading zero
it is the incorrect number of significant figures
no working shown
so you need to make sure your answer covers these.
