A) \[10.5\,\,g\]
B) \[13.5\,\,g\]
C) \[11.5\,\,g\]
D) \[14.2\,\,g\]
Correct Answer: C
Solution :
Gram atomic weight of sodium \[(Na)\] is\[23\,\,g\] and that of oxygen \[(O)\] is\[16\,\,g\] Number of moles of oxygen\[=\]\[\frac{\text{Weight}\,\,\text{(given)}}{\text{GAW}}=\frac{8}{16}\] Weight of sodium \[(Na)=\] Number of moles\[\times \,\,GAW=0.5\times 3=11.5\,\,g\]You need to login to perform this action.
