Question

The number of moles in 11g of nitrogen gas is ___
(0.39,0.49,0.29) Atomic mass N=14​

Answer 1

Answer:

moles=given mass/ molar mass

11/14

Answer 2

Given :

Atomic mass of nitrogen = 14 u = 14 g

To find :

No. of moles in 11 g of nitrogen gas

Calculation :

14 g of nitrogen gas makes 1 mole of it.

no. of moles 11 g of nitrogen gas would make = 11 × 1 / 14

no. of moles = 11 / 14

no. of moles = 0.78 moles

Nearest possible answer is 0.49
