Question

calculate number of molecules present in 196g of sulphuric acid​

Answer 1

Answer:

the no.of molecules of sulphuric acid will be 12.04×10^23

Explanation:

molar mass of sulphuric acid (H2SO4)

=98 g

now 196g will be 2 moles

in 1 mole of sulphuric acid the no. of Molecules present=6.02×10^23

so in 2 moles of sulphuric acid the no of molecules present =2×6.02×10^23

=12.04×10^23
