Q.
A mixture of MgO and Mg weighing 10g is treated with excess of dil HCl. Then 2.24 lit of H
2
gas was liberated under STP conditions. The mass of MgO present in the sample is
A.
2.4g
B.
7.6g
C.
8g
D.
2g
E.
None of the above
View Answer
Correct choice: B
Explanation:
Among Mg and MgO, only Mg gives Hydrogen gas with acid .
Mg + 2HCl → MgCl
2
+H
2
1 mole i.e 24gm of ‘Mg’ gives 22.4 lit of H
2
at STP.
Wt .of Mg giving 2.24 lit of H
2
at STP=( 2.24X24/22.4)=2.4gm
Wt .of Mg=2.4gm and wt of MgO in the mixture= 10-2.4= 7.6gm.
