GAS LAW DIFFUSION AND GRAHAM'S LAW . INTRODUCTION LABORATORY SIMULATION 1) Given that the molar mass of ammonia is 17.030 g/mol, calculate the molar mass of hydrogen chloride using your Phase 5 (Longer Tube) Lab Data. Molar mass of HCI = g/mol ALab Data C Experimental Set-up Time elapsed (min) Distance between cotton balls (cm) Distance to cloud (cm) Distance traveled by HCI (cm) Distance traveled by NH3 (cm) Diffusion rate of HCI (cm/hr) Diffusion rate of NH3 (cm/hr) HCI-NH3 5 (exact) 24.30 9.60 9.60 14.70 115 176.4 NH3-HCI 5 (exact) 24.40 14.10 10.30 14.10 123.6 169.2 How to measure distance and calculate rate Longer Tube 6 (exact) 32.80 12.90 12.90 19.90 129.0 199.0
