A Canadian, driving in the U.S.A., fuels their car at a cost of US$3.72 per gallon (US).

The current monetary exchange rate is 0.928 US$/Can$.
The density of the fuel is 0.626 g/mL.
What is the mass of Can$90.00-worth of this fuel?

Answer 1

Two concepts here.
mass = volume x density.
Exchange from US$ to CAN$ or the reverse.
Where are you having trouble?

Answer 2

i don't understand what the question is asking?

Answer 3

You have CAN $90.00 and you're driving in the US. You buy fuel in the US at $3.72 US dollars/gallon. What's the mass of fuel that can be bought for that CANADIAN $90.00. The problem doesn't give the unit for mass; I assume grams since the density is in g/mL.
