Calcualte the number of moles of magnesium present in a magnesium ribbon weighting 12g. Molar atomic mass of magnesium is 24 g `mol^(-1)`.

Text Solution

Verified by Experts

Mass of magnesium (Mg)=12g
Molar mass of magnesium(Mg)=`24gmol^(-1)`
`"No. of moles of magnesium(Mg)"=(("Mass"))/(("Molar aromic mass"))=((12g))/((24gmol^(-1)))=0.5"mol"`
