chemistry question please...?
A sample of chloroform is found to contain 12.9 g of carbon, 114.4 g of chlorine, and 1.09 g of hydrogen. If a second sample of chloroform is found to contain 34.4 g of carbon, what is the total mass of chloroform in the second sample?

if the total of the elements is 128.39, and 12.9 is carbon, that's
12.9/128.39 = 34.3/X where X is the total mass of chloroform in the 2nd sample.
X/34.3 = 128.39/12.9, then X = (128.39 x 34.3)/12.9 =
341.38 grams in sample 2.
