mass of the gas?
square both sides.
If 0.896 g of a gas occupies a 250 mL flask at 20 degrees Celsius and 760 mm Hg of pressure, what is the molar mass of the gas?

A gas of unknown molecular mass was allowed to effuse through a small opening under constant-pressure conditions. It required 125 s for 1.0 L of the gas to effuse. Under identical experimental conditions it required 34 s for 1.0 L of O2 gas to effuse. Part
Food manufacturers sometimes add calcium acetate to puddings and sweet sauces as a thickening agent. What volume of 0.500 mol/L calcium acetate, Ca(CH3COO)2 (aq), contains 0.300 mol of acetate ions? So I've been over this a hundred times and I still can't
If 0.896 g of a gas occupies a 250 mL flask at 20°C and 760 mmHg of pressure, what is the molar mass of the gas?
Calculate the change in entropy that occurs when 17.68 g of ice at -12.7°C is placed in 54.05 g of water at 100.0°C in a perfectly insulated vessel. Assume that the molar heat capacities for H2O(s) and H2O(l) are 37.5 J K-1 mol-1 and 75.3 J K-1 mol-1,
Oxygen has a molar mass of 32 g/mol. If 12 moles of oxygen are in a 0.1-m3 container with an rms speed of 480 m/s, what is the pressure of the gas? I don't understand what I'm doing wrong Im using p=nM(vrms^2)/3V and im getting 2.9E8? someone pls explain
An unknown gas diffuses ar a rate of 0.5 times that of nitrogen at the same temperature and pressure. Calculate the molar mass of the unknown gas.
