The correct answer is 4d subshell
Gas, solid, and liquid drawing.
The changing current affects the density of the nitrate in the water.
<em>We know<u> One mole of Argon occupy the volume of 22.4 L
</u></em>
<em>Therefore , 22.4 L of Argon weighs 40 g.</em>
<em>∴ 1 L of Argon weighs , 40/22.4 </em>
<em>∴ 100 L of Argon weighs (40/22.4 ) × 100</em>
<em>= 178.57 g.</em>
<em>Hence <u>moles of Argon is 178.57 g.
</u>Hope it Helps :-)</em>
