You're on a roll — here's the solution for question 18: Step 1: Determine the number of moles of the gaseous compound. At room temperature and pressure (r.t.p.), 1 mole of any gas occupies 24000 cm^3. Given volume = 30 cm^3. Moles = Given VolumeMolar Volume at r.t.p. Moles = 30 cm^324000 cm^3/mol Moles = 0.00125 mol Step 2: Calculate the molar mass of the compound. Given mass = 0.035 g. Molar Mass = MassMoles Molar Mass = 0.035 g0.00125 mol Molar Mass = 28 g/mol Comparing this to the given options: A: 14g B: 32g C: 28g D: 56g The calculated molar mass matches option C. The final answer is C: 28g. Got more? Send 'em!
