The density of a substance is the ratio of its mass to its volume. The formula for density is: D-mass/volume. If the density and the
volume of a liquid are known, its mass can be found by
A)
adding its density to its volume,
dividing its density by its volume.
multiplying its volume and density
D)
subtracting its density from its volume.

Yes, that is correct. There are 1.25 moles in one liter of solution, and there are about 98 grams in one mole of H2SO4. Using this information we can readily eliminate A and B as answers, as there would be far more than 36 grams in 2.9 and 5.8 liters of this solution. 98 x 1.25 = 122.5 grams of H2SO4 in one liter, and we can then divide 36 into 122.5 to arrive at 0.29L.
