The number of moles of ammonia present in a 7.686 g sample of ammonia, which has a molar mass of 17.030 g/mol is 0.45 moles.

HOW TO CALCULATE NUMBER OF MOLES:

  • The number of moles of a substance can be calculated by dividing the mass of the substance by its molar mass. That is;

  • no. of moles = mass (g) ÷ molar mass (g/mol)

  • According to this question, there are 7.686g of ammonia sample and has a molar mass of 17.030 g/mol. The number of moles is as follows.

  • no. of moles = 7.686g ÷ 17.030g/mol

  • no. of moles = 0.45 moles.

  • Therefore, the number of moles of ammonia present in a 7.686 g sample of ammonia, which has a molar mass of 17.030 g/mol is 0.45 moles.
