4 g of O_2 and 2g of H_2 are confined in a vessel of capacity 1 litre at 0^@C. Calculate the number of moles of each gas

4 g of O_2 and 2g of H_2 are confined in a vessel of capacity 1 litre

1.	4 g of O_2 and 2g of H_2 are confined in a vessel of capacity 1 litre at 0^@C. Calculate the number of moles of each gas
Answer» SOLUTION :CALCULATION of number of moles : Number of moles = `("Mass in grams")/("GRAM molecular mass")` `:. " Number of moles of " O_2 = 4/32 =0.125` and, Number of moles of `H_2 =2/2 =1`
