present in 2.24 L of nitrogen gas at STP?
(b) 0.099
(d) 1.00
(a)
(c)
9.9
0.001​

Answer 1

Answer:

0.1 moles

Explanation:

Given :

Given volume of Nitrogen gas is 2.24 L

We have to find numbers of moles.

We know :

No. of moles = Given Volume / volume at S.T.P.

or No. of moles = Given volume / 22.4 L

Putting values now :

No. of moles = 2.24 L / 22.4 L

No. of moles = 0.1 moles .

Hence the final answer is 0.1 moles .

Answer 2

$\huge{\mathfrak{\underline{\underline{\red{Answer :-}}}}}$

Number of moles = 0.1

$\large{\mathrm{\gray{\underline{Given:-}}}}$

Volume of nitrogen gas is 2.24 L .

$\large{\mathrm{\gray{\underline{To \: Find :-}}}}$

Number of moles.

$\large{\mathrm{\gray{\underline{Solution :-}}}}$

Using Formula :-

$\large{\boxed{\boxed{Number of moles \: =\: \frac{Given \: volume}{Volume \: of \: STP}}}}$

________________[Putting values]

⇒ Number of moles = 2.24 L / 22.4 L

$\bf{Number \: of \: moles \: = \: {\frac{{\cancel{2.24 L}}}{{\cancel{22.4L}}}}}$

⇒ Number of moles = 0.1

$\large{\boxed{\boxed{Number of moles \: = \: 0.1}}}$
