Aformer high school teacher was discovered making meth, and the dea recently analyzed some confiscated material from a drug bust he was associated with. they found a compound with the empirical formula c17h14o7 that has a molar mass of 990.87 g/mol. what is the value of n (the multiplier) necessary to find the molecular formula?

3 is the value of n necessary to find the molecular formula.

Explanation:

The equation used to calculate the valency is :

We are given:

Mass of molecular formula = 990.87 g/mol

Mass of empirical formula of :

Putting values in above equation, we get:

3 is the value of n necessary to find the molecular formula.

The molecular formula is :
