m(P) =
m(KCl) =
n(KClO3)=
n (P2O5) =
m(KClO3) =
m(P2O5) =
n (P) =
n(KCl) =
m(P) =
m(KCl) =
n(KClO3)=
n (P2O5) =
m(KClO3) =
m(P2O5) =

Verified answer
6P+5KCLO3-->5KCL+3P2O5M(P)=31g/mol
M(KCLO3)=122.5g/mol
M(KCL)=74.5g/mol
M(P2O5)=142g/mol
n(P)=6 mol
n(KCL)=5 mol
m(P)=n*M=6*31=186 g
m(KCL)=n*M=5*74.5=372.5 g
n(KCLO3)=5 mol
n(P2O5)=3 mol
m(KCLO3)=n*M=5*122.5=612.5 g
m(P2O5)=n*M=3*142=426 g
