I AM GIVING BRAINLIEST! PLEAS HEL I NEEED HEL PLEAS Find the molecular formula for a compound with-
4.04 g N, 11.46 g O, molar mass 108.0 g/mol.
? moles N =
? moles O =
N : O =
empirical formula =
molecular mass of empirical formula =
The molar mass ratio of (molecular formula/empirical formula) =
molecular formula =

moles of N

4.04 g / 14.01 = 0.288

moles of O

11.46 / 16 = 0.72 moles

divide both of them by the lowest number of moles to get the ratio

0.288 / 0.288= 1

0.72 / 0.288 = 2.48

now multiply both by 2, to make it a whole number =

ratio = 2 : 5

empirical formula = N2O5

the molar mass of the compound = 108.01

molar mass of the empirical formula = 108.02

when you divide this to get the factor the factor is also 1, so you dont really change anything

FORMULA = N2O5

Explanation:

I had it written done from my school notes

I really hope this helps

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
