Can someone help me to answer this correctly, please, and explain it.

A sample of 5.869 grams of a compound containing carbon and hydrogen reacts with oxygen at elevated temperatures to yield 20.29 grams of CO2 and 2.967 grams of H2O. (a) Calculate the masses of C and H in the sample. Grams: C= g; H= g (b) Does the compound contain any other elements? (c) What are the mass percentages of C and H in the compound? Mass percentages: C=%;H=% (d) What is the empirical formula of the compound? Enter the elements in the order presented in the question. empirical formula = A sample of 5.869 grams of a compound containing carbon and hydrogen reacts with oxygen at elevated temperatures to yield 20.29 grams of CO2 and 2.967 grams of H2O.
