Can somebody tell me if I am solving this chemistry problem correctly?
A sample of an organic compound (known to be composed of only carbon, oxygen, and hydrogen) weighing 8.28 g is found by elemental analysis to contain 4.70 g of carbon, 2.52 of oxygen, and 1.06 g of hydrogen. What is the fractional, decimal, and percentage composition of the 3 elements?
I divided each of the elements from the total weight and multiplied by 100 and got the following answers:
Carbon-- 57/100 (fractional) 0.57 (decimal) and 57% (percentage)
oxygen-- 3/10 (fractional) 0.30 (decimal) and 30% (percentage)
hydrogen-- 13/100 (fractional) 0.13 (decimal) and 13% (percentage)
Please note any errors. Thanks
