The molecular mass of a compound is 92 g/mol. Analysis of the compound shows that it consists of 0.608 g of N and 1.388 g of O.
Pavel [41]

The empirical and molecular formula would be  NO_2 and  N_2O_4 respectively.

<h3>Empirical formula</h3>

The compound contains N and O.

N                                                        O

0.608/14 = 0.0434                        1.388/16 = 0.0867

Divide by the smallest.

N = 1                                             O = 2

Thus, the empirical formula would be NO_2

To get the molecular formula:

Empirical formula mass = 14 + (16x2) = 46

n = molar mass/empirical formula mass

          = 92/46 = 2

Thus, the molecular formula would be N_2O_4

What volume is occupied by 0.25 moles of nitrogen gas at 360 K and 1.50 atm
Annette [7]
It varies with container, temperature, pressure and amount of gas. But, the volume occupied by a gas at a fixed temperature and pressure remains constant which is 22.4 L for 1 mole at STP.
