Question

The number of oxygen atom in 49gram mass weight of h2so4 ,N=avagagadro number

Answer 1

Explanation:

The molecular mass of H2SO4 is 98.1 amu, meaning one mole of H2SO4 molecules has a mass of 98.1 g. (1 mole = 6.022 x 10^23 molecules). If you divide 49 g by 98.1 g/mole you get .4995 moles. Multiply this by 6.022 x 10^23 to get 3.008 x 10^23 molecules of H2SO4 in 49 g. If you multiply this by 4 (there are 4 oxygen atoms in each molecule) you get 1.203 x 10^24 atoms of oxygen.
