Molar Mass of CO2 Objective : Calculate the molar mass of CO2 (dry ice). Make sure this is handwritten in the lab notebook. Procedure : Note : During the lab, look for a qualitative observation that proves CO2(g) is denser than air. (1) Weigh the empty 250mL Erlenmeyer flask with a rubber stopper on. What is the volume of the air inside? (2)Obtain
Calculate an experimental value for the molar mass of CO2 based on the mass, volume, and temperature data from the Determination of Molar Mass of CO2 lab, Mass (before rxn): test tube + HCl (aq) + stir bar + capsule 26.339 g Mass (after rxn): test tube + HCl (aq) + stir bar + capsule 26.025 g Volume of water displaced from squirt bottle 144 mL ...

There are 2 steps to solve this one. The mass per unit volume of an object is its density. Given the following data from the Molar Mass of CO2 Lab: Mass (before rxn): test tube + HCl (aq) + stir bar + capsule 26.042 g Mass (after rx) test tube + HCl (aq) + stir bar + capsule 25.693 g Volume of water displaced from squirt bottle 139 ml ...
The molar mass of KO2 = 71.10 g/mol and K2CO3 = 138.21 g/mol. Determine the theoretical yield and the percent yield if 21.8 g of K2CO3 is produced from reacting 27.9 g KO2 with 29.0 L of CO2 (at STP).
Given the following data in the Determination of Molar Mass of CO2 lab : Mass (before rxn): test tube + HCl (aq) + stir bar + capsule 26.986 g Mass (after rxn): test tube + HCl (aq) + stir bar + capsule 25.783 g Volume of water displaced from squirt bottle 144 mL Temperature of CO2 (g) 293.6 K CO2 (g) pressure 0.986 atm Calculate the mass of ...
For diatomic carbon dioxide gas (CO2, molar mass 44.0g/mol) at T=300K, calculate (A) the most probable speed vmp; (B) The average speed Vav; (C) The root-mean-square speed vrms. There’s just one step to solve this.
Step 1. The ideal gas law gives the relation between volume, pressure, number of moles and absolute temperat... Carbon dioxide gas is collected in a laboratory experiment to determine the molar mass of the compound. At 294 K and 1.01 atm, 1.008 g of CO 2 was collected when a 500.ml flask was filled with the evolved CO2.
Question: Using the following equation for the combustion of octane, calculate the heat associated with the combustion of 100.0 g of octane assuming complete combustion. The molar mass of octane is 114.33 g/mole. The molar mass of oxygen is 32.00 g/mole. 2 C4H18 + 25 O - 16 CO2 + 18 H2O AH"rxn--11020 -9639 kJ -535.4 kJ -4819 -385.5 -602.3.
