A solution has a specific gravity of 1.35. Calculate the mass of 25.0mL of this solution.?

Answer 1

you probably mean specific density...
in which case it is 25*1.35 = 33.75g or 0.03375kg

what you do is simply convert thevolume of the substance into litres or millilitres... which is already given here, and multiply it with the specific density... where calculating with millilitres gives the result in grams, and converting to litres results in kilograms.

this is of course only true for a gravity of 1ge. so to be really precise you have to multiply the result with the value of the local gravity.

for example, in a 1.5ge environment the same question would have the answer 25*1.35*1.5=50.62g or 0.05062kg
