What is the molar mass of an unknown gas in a 1.8L container if 589 g has a pressure of . .090atm at 20C?
Vickyd2008
PV=nRTR = 0.08205746 Latm/kmol
20C + 273.15 = 293.15K
n = (0.090 ATM * 1.8 L) / ( 0.08205746 Latm/kmol * 293.15K)
n = 0.00673mol
589g / 0.00673 mol
87459.75 g/mol
well this is how you do it
now this is an unbelievable high molar mass so check the values of mass and pressure and you may need to recompute

If an insufficient amount of a liquid unknown had been used how would this affect the value of the experimental molar mass?
When the unknown liquid is heated and turned into vapor, the unknown will not occupy the whole container. In the equation to find the molar mass (nRT)/PV, the volume will be greater than the actually volume of the unknown, thus leaving a molar mass that is less than the actual molar mass
An unknown gas with a mass of 8.32 g is held at 25 degrees Celsius in an 8.42 L tank under 1147.6 mmHg pressure What is the molar mass of the gas?
0.52 mol.
The combustion data for an unknown compound containing carbon hydrogen and oxygen was analyzed and the empirical formula for the unknown was found to be C3H5O The molar mass of the unknown was found?
C6h12o3
What does molar volume mean for a gas?
Molar gas volume is the volume of ONE moel of gas. It only depends on the pressure and temperature, not on the kind of gas. Molar volume at standard temperature and standard pressure is always 22,4 Litres (for any gas)
Molar solubility of helium at a pressure of 1.0 ATM?
Find the constant, which i think is 3.7*10^-4 and multiply it by 1.0. and you should get your answer

What is the molar mass of 18.12 g of gas exerting a pressure of 3.05 ATM on the walls of a 5.85 L container at 280 K?
The molar mass is 23,33 g.
30.4 grams of X2O3 gas makes 2 atm pressure at 273 C in a 8.96 liter container. So, howmany g.mol is the molar mass of the X atom of the X atom (O:16)?

How does one determine a molecular formula from the empirical form?
molar mass of unknown/molar mass of empirial = # of empirical units in the molecular formula. Example: empirical formula is CH2O with a molar mass of 30. If the molar mass of the unknown is 180, then 180/30 = 6 and molecular formula will be C6H12O6

How do you find out the molar mass of a gas given density temperature and pressure?
MolarMass = [density x gas constant x temperature(in kelvin)] / pressure (in atm)
What effect would there be on a molar mass determination if the solute were to dimerize?
The molecules of the solvent are combining, cutting the concentration of the solvent in half. This, therefore, doubles the molar mass of the solute. Example: 1. Suppose the freezing point of a solution of 2.00 g of an unknown molecular substance in 10.00 g of the solvent benzene is measured. If the solution freezes at a temperature of 6.33°C lower than pure benzene itself, calculate the molar mass of the unknown substance. - 6.33/5.12= 1.24m, solve for x- 1.24m= x/0.01 kg, x=0.0124 mol, 2.00 g/0.0124mol=161.29 g- your molar mass - now cut the amount of solvent, 0.01Kg(10.00g), in half 1.24m=x/0.005 kg, x=0.0062 mol, 2.00 g/0.0062mol = 322.581 g, your larger molar mass
What is the partial pressure of carbon dioxide in a container that holds 5 moles of carbon dioxide 3 moles of nitrogen and 1 mole of hydrogen and has a total pressure of 1.05 ATM?
I presume that molar mass is needed n = pV/RT = 1 atm x 0.250 L/ 0.08206 x 273 K= 0.0112 molar mass = 2.50/ 0.0112 =224 g/mol total moles = 5.0 3.5 / 5.0 = partial pressure CO2 / 7.0 partial pressure CO2 = 4.9 atm Goodluck from michigan tech - Charlesworth sucks
How does the molar concentration at Standard temperature and pressure depend upon the identity of the gas?
Molar concentration is defined as the amount of a gas divided by the volume of gas. According to the gas identity, at standard temperature and pressure, even if the amount of the gas is constant, the volume of gas changes. Thus, the molar concentration changes depending on the gas identity.
