Question

Calculate the number of mole in 460 g of H2SO4

Answer 1

Answer:

no. of moles= mass of substance in grams

--------------------------------------------

molecular mass of substance

molecular mass of H2S04= sum of atomic mass

of individual components .

molecular mass of H2S04= 1×(2)+32+16×(4)

= 2+32+48

:. 98

no of moles = 460/98

= 4.69

no . of moles = 4.9
