How many moles of nitrogen, n, are in 65.0 g of nitrous oxide, n2o?

65 g of nitrous oxide contain 2.96 moles of nitrogen.

Explanation:

Given data:

mass of N₂O = 65 g

moles of nitrogen = ?

Solution:

First of all we will calculate the moles of N₂O.

number of moles = mass / molar mass

number of moles = 65 g/ 44.01 g/mol

number of moles = 1.48 mol

One mole of nitrous oxide contain two mole of nitrogen.

we will multiply the moles of nitrous oxide with two.

1.48 mol × 2 = 2.96 moles

So 65 g of nitrous oxide contain 2.96 moles of nitrogen.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.
