Question

। नाइट्रोजन के 0.6 अणु का द्रव्यमान है-​

Answer 1

Answer:

Multiply the number of moles given by Avogadro's number ( 6.02×10's power 23

) because Avogadro's number is equal to the number of molecules in 1 mole of substance.

Hence

0.6×6.02×10's power 23

Answer 2

The mass of given amount of nitrogen gas is 16.8 grams

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Moles of nitrogen gas = 0.6 moles

Molar mass of nitrogen gas = 28 g/mol

Putting values in above equation, we get:

$0.6mol=\frac{\text{Mass of nitrogen gas}}{28g/mol}\\\\\text{Mass of nitrogen gas}=(0.6mol\times 28g/mol)=16.8g$
