1.	Find total no. of h2 atoms in 100 ml of methanol CH3OH. Density of methanol is 0.8 gm per ml.
Answer» Density = 0.8g , volume =100ml , m=dv =0.8100=80g/ml ,m=80 and molecular mass ch3oh = 12+3+16+1=32, mole = given mass /molecular mass 80/32=2.5 ,1 mole contain Na atom then 2.5 mole contain 2.5Na
