If the volume of 26.100 grams of chloroform has a density of 1.49 g per ml, then what is the mass? I got 18.125. Is this correct?

My other question is, if the mass of an aspirin is 250 mg, then what is the mass in kg? I got, .00025. Is this correct?

Thanks, Elise

I get 17.5 ml for the volume

250 mg = 250*10^-6 kg = 2.5*10^-4 kg

Your answer is correct, but in decimal rather than scientific notation. Very small and very large numbers are better written in scientific notation, in my opinion.
