Question

11.2 L of a gas at STP weight 14g. The gas can be (A) N2 (B) CO (C) B2H6 (D) N20​

Answer 1

Answer:

answer is B and C

Explanation:

Correct option is

B

CO

C

B

2

H

6

No. Of moles of that gas=

22.4 L

11.2 L

=

2

1

mole

Given mass =14g

We know,

No. Of moles =given mass /molecular mass

2

1

mole=

molar mass

14

molar mass=28g

the molar mass of CO is 28

also, the molar mass of B

2

H

6

is 28g

Thus, the gas could be CO or B

2

H

6

Hence, the correct options are B and C
