Define mole. Calculate number of moles is 49 g `H_(2)SO_(4)` (Atomic Mass of `H=1, O=16,S=32`)

Text Solution

Verified by Experts

Mole is the amount of substance that contains as many particles or entities as there are atoms in exactly 12-g of `.^(12)C` isotope.
Molar mass of `H_(2)SO_(4)=2+32+64=98` No. of moles of `H_(2)SO_(4)=49/98=0.5`
