Question

The teacher asked Rohan to tell the mass of 0.5 moles of Nitrogen gas, what will be the correct answer?​

Answer 1

Answer:

7 grams

Explanation:

molar mass=14 mole=0.5

mole (0.5)=mass/molar mass (14)

we get 7.0grams

Answer 2

Answer:

The correct answer would be 0.5 moles of nitrogen gas in 14g.

Explanation:

What is nitrogen gas?

During the sample preparation phase of chemical analysis, nitrogen is frequently utilised. It is used to concentrate and condense liquid sample volumes. Additionally crucial to the chemical sector is nitrogen. It is used to make explosives, nylon, nitric acid, fertilisers, and colours.

Molecular form, that is $N_{2}$

Therefore, the molecular mass of $N_{2} = 28g$

We know that,

number of moles($n$)= $\frac{givenmass}{molar mass}$

$0.5 mol = \frac{given mass}{28g mol^{-1} }$

given mass= $0.5mol$ x $28g$ $mol^{-1}$

given mass= 14g

hence, the mass of 0.5 moles of nitrogen gas in 14g.
