What is the molecular formula of a compound with the empirical formula c13h19o2 and molar mass of 414.64 g?

Hint: the empirical formula is the simplest form to their of the formula so try to make them into the smallest number you can by dividing them etc. and after that you will be able to calculate the molar mass from the help of the handy dandy triangle

The correct answer is c

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
