Answer 1

Q. The mass of 94.5 ml of a gas at S. T. P is found to be 0.2231 g. Calculate its molecular mass.

Ans :- 52.9

Explanation:-

$we \: know \: that$

$density \: of \: gas = \frac{volume \: }{mass}$

$= \frac{0.2231}{94.5} ml$

$molecular \: mass = molar \: volume \: \times density$

$molar \: volume \: = 22.4l$

$= 22.4 \times 1000ml$

Therefore,

$molecular \: mass = \frac{22.4 \times 1000 \times 0.2231}{94.5}$

$= 52.9 \: ans \:$

Solution:-

______________

Density of gas =Volume /mass

=>0.2231/94.5 ml

__________________

molecular mass =>Molar mass x density

=>22.4 x 1000ml

So molecular mass is

=>22.4 x 1000 x 94.5/0.2231

=>52.9

hence we get answer

hope helps✊⭐
