1. Calculate the molar mass of KClO3: 39.098+ 35.453 + 3(16) = 122.551 g KClO3
2. 5gKClO3 x 1mol KClO3/ 122.551g KClO3 = 0.041mol of KClO3

Molar mass of KClO3


\\ \tt\hookrightarrow 39+35+3(16)


\\ \tt\hookrightarrow 74+48


\\ \tt\hookrightarrow 122g/mol

Now


\\ \tt\hookrightarrow No\:of\:moles=(Given\:mass)/(Molar\:mass)


\\ \tt\hookrightarrow No\:of\:moles=(5)/(122)


\\ \tt\hookrightarrow No\:of\:moles=0.04mol
