A substance known to cause lung cancer has the following percent composition: 28.03% Mg, 21.60% Si, 1.16% H, and 49.21% O. Calculate its empirical formula [a] If the molar mass is 520.8 g/mol, calculate the molecular formula [b]. Ignore the subscripts when writing the answer, for example write water as H2O A substance known to cause lung cancer has the following percent composition: 28.03% Mg, 21.60% Si, 1.16% H, and 49.21% O.
