The empirical formula is the formula in its most simplified terms. The molecular formula is how many moles there actually are (the empirical formulat multiplied by a factor).
Because an empirical formula is the simplest form of a compound, we know that the molecular formula contains more atoms than it does. Since we are given the molar mass, we can use this formula.

Yes, the empirical formula is the most basic ratio of the elements in a compound, while the molecular formula is the ratio in a compound. For instance C5H10O could be both the empirical and the...
If you are given the empirical formula and are asked for the actual formula, then the molecular mass of the compound will be given too. Take this example problem: Empirical Formula: CH2O Molecular...
The density of acetylene gas is 1.17 grams/L at STP. 1.17g/1L * 22.4L/1mol = 26 molbecause in pure gases 1 mol= 22.4 liters.the empirical formula is CHthe molar mass of CH is 12+1=13 g/mol26/13=2C2H2
