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.
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
