Answer:
Option A = 2.2 L
Explanation:
Given data:
volume of one mole of gas = 22.4 L
Volume of 0.1 mole of gas at same condition = ?
Solution:
It is known that one mole of gas at STP occupy 22.4 L volume. The standard temperature is 273.15 K and standard pressure is 1 atm.
For 0.1 mole of methane.
0.1/1 × 22.4 = 2.24 L
0.1 mole of methane occupy 2.24 L volume.
Answer:
C21H2802
Explanation:
C=12g/mol
H=1g/mol
O=16g/mol
Part (C) of compound-80.18%
(0.8018 x 312)/12=21
Part (H) of compound-8.97%
(0.897 x 312)/1=28
Part (O) of compund-10.3%
(0.103 x 312)/16 = 2
Therefore the emp. formula is C12H28O2
