Question

Calculate the ratio of effusion rates of oxygen (o2) to hydrogen (h2)

Answer 1

The ratio of effusion of rates of oxygen (O2) to Hydrogen (H2) is calculated as follows

rate of O2/ rate of H2 = square root of molar mass of H2/molar mass of O2

= square root = 2 /32 = 0.25

Answer 2

0.251

Step-by-step explanation:

According to the Graham's law, the rate of effusion of a gas (r) is inversely proportional to the square root of its molar mass (M). The ratio of effusion rates of oxygen (O₂) to hydrogen (H₂) is:

`(rO_(2))/(rH_(2)) =\sqrt{(M(H_(2)))/(M(O_(2)))} =\sqrt{(2.02g/mol)/(32.00g/mol)} =0.251`
