Question

calculate the mass of atoms present in 0.5 moles of Nitrogen (N). (N=14u)​

Answer 1

GIVEN :

moles of Nitrogen (N) = 0.5

molar mass of N = 14

To find:

the mass of atoms present in 0.5 moles of Nitrogen (N).

FORMULA USED :

NUMBER OF MOLES = GIVEN MASS/ MOLAR MASS

SOLUTION :

NUMBER OF MOLES = MASS/ MOLAR MASS

0.5= MASS / 14

0.5 ×14= MASS

7 = MASS

ANSWER

7 = MASS OF ATOMS PRESENT IN 0.5 MOLES OF NITROGEN.
