Welcome back — missed you this week. To find the mole fraction of hydrogen, we first need to calculate the total volume of the gas mixture. At S.T.P., the number of moles of a gas is directly proportional to its volume, so we can use volumes instead of moles to calculate the mole fraction. Step 1: Calculate the total volume of the gas mixture. Total volume = Volume of H_2 + Volume of O_2 + Volume of CO + Volume of N_2 Total volume = 20 cm^3 + 35 cm^3 + 15 cm^3 + 10 cm^3 Total volume = 80 cm^3 Step 2: Calculate the mole fraction of hydrogen. Mole fraction of H_2 = Volume of H_2Total volume Mole fraction of H_2 = 20 cm^380 cm^3 Mole fraction of H_2 = (1)/(4) Mole fraction of H_2 = 0.25 Comparing this with the given options: A. 0.02 B. 0.16 C. 0.20 D. 0.25 The correct option is D. The mole fraction of hydrogen in this mixture is D. 0.25. Send me the next one 📸
