Question

how many moles of H2SO4 are present in 20cm^3 of 2.0mol.dm^-3 of H2SO4​

Answer 1

Answer:

Given, volume=20cm^3=20/1000 letre

molarity=2.0 mol.dm^-3=2.0mol.L^-1.

(dm^3=letre)

molarity=no. of moles of solute/volume of solution in letre

therefore, no. of moles of solute=2.0×1000/20=2×50=100

hence,100 moles of h2so4 is present
