4. a student performed an experiment to determine the molecular weight of a gaseous compound. Using the ideal gas law PV=nRT, and knowing the pressure, temperature, and volume of the vapor, the student calculated the number of moles of gas, n, to be 0.0443 mol. The weight of the gas was 1.42 g. What is the molecular weight of this compound? solve everything step by step
Accepted Answer
The molecular weight of a compound is the mass of one mole of that compound. We can calculate it using the following formula:
Molecular weight = Mass / Moles
In this case, the mass of the gas is 1.42 g and the number of moles is 0.0443 mol. Therefore, the molecular weight of the compound is:
Molecular weight = 1.42 g / 0.0443 mol = 32.0 g/mol
