Question

calculate the total number of atoms present in 0.8 mole of H2S

Answer 1

Hi there,

Moles means Avogadro's number i.e. 6.023*10^23*0.8

means 0.8 *6.023*10^23=4.8148*10^ 23 molecules.

H2S has 2 H and S for each molecule. so S has 4.8148*10^ 23 atoms and H has 9.6368 * 10^

23 atoms (answer).
