A) \[2.5\times {{10}^{-2}}\]
B) 0.02
C) \[3.125\times {{10}^{-2}}\]
D) \[1.25\times {{10}^{-2}}\]
Correct Answer: C
Solution :
Molar mass of \[{{\operatorname{Mg}}_{3}}{{\left( P{{O}_{4}} \right)}_{2}}=80\] \[\therefore 0.25 mole oxygen atoms =\frac{0.25}{8}=3.125\times 1{{0}^{-2}}\]Mole of \[{{\operatorname{Mg}}_{3}}{{\left( P{{O}_{4}} \right)}_{2}}\]You need to login to perform this action.
