To calculate the molecular formula of the compound CxHy given the mass percent of hydrogen (W(h)), the molar mass of the compound (Mr), and the mass percent of the compound (W(h)), we can use the following formula:

W(h) = (W(h) (2.016/18.016)) / ((W(h) (2.016/18.016)) + ((100-W(h)) * (12.011/46.068)))

Given that W(h) = 17.2%, Mr = 5.8, and the molar masses of hydrogen and carbon are 2.016 g/mol and 12.011 g/mol respectively, we can substitute these values into the formula:

17.2 = (17.2 (2.016/18.016)) / ((17.2 (2.016/18.016)) + ((100-17.2) * (12.011/46.068)))

Solving this equation will give us the values of x and y, which will help us determine the molecular formula of the compound CxHy.
