Van Der Waals EQ moles! a)I need to determine the number of moles in some vapor.(n,vapor)(mol) P=.988403 atm V=148L T=371.65 a=9.523 b=0.06702 R=0.08206 I know the equation is P=(nRT/(V-nb))-(an^2/V^2) b) mass of vapor (m,vapor)(g) c) molar mass of compound (g/mol) I am having trouble calculating the moles though. Please help!

What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
The molar mass of C3H8O2 is?
to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu) to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu)
What is the molar mass of lithium oxide Li2O?
Lithium has a molar mass of 6.94 g/mol. Oxygen has a molar mass of 16.00 g/mol. Since Lithium Oxide has 2 Lithium atoms, the molar mass is: (6.94 x 2) + 16.00 = 29.88 g/mol.
What is the mass of helium?
helium = 4 molar mass
What is the mass percent of hydrogen in ammonium phosphate NH4 3PO4?
To find the mass percent of hydrogen in ammonium phosphate NH4 3PO4, first calculate the total molar mass of the compound. Then, determine the molar mass contributed by hydrogen. Finally, divide the molar mass of hydrogen by the total molar mass of the compound and multiply by 100 to get the mass percent.
How can one determine the molar mass from molality?
To determine the molar mass from molality, you can use the formula: Molar mass (molality x molar mass of solvent) / molality of solute. This equation helps you calculate the molar mass of a substance based on its molality in a solution.
How do you solve for molar mass using the equation PV mMRT?
The ideal-gas law is PV=nRT. Since the moles of a substance can be found by the equation n=m/M where m = mass and M = molar mass, you can substitute this in to get: PV = mRT/M So you can rearrange this equation to read: M = mRT/PV
How is the law of conservation of mass shown by a balanced equation?
In stoichiometry, the equation is balanced by using molar ratios. Because each item on either side of the equation has a specific molar mass, it can be demonstrated that all mass is conserved through the chemical reaction.

How can one determine the molar mass of a gas using the ideal gas law?
To determine the molar mass of a gas using the ideal gas law, you can rearrange the equation to solve for molar mass. The ideal gas law is PV nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature. By rearranging the equation to solve for molar mass (M), you get M (mRT)/(PV), where m is the mass of the gas. By measuring the pressure, volume, temperature, and mass of the gas, you can calculate the molar mass using this formula.
What is the mass of 1 mole of gas?
39.95 because that is the molar mass of Argon
What effect Dimers molar mass determination volatile liquids?
I'm trying to figure out how it affects molar mass as well. However, I do know that it decreases the pressure which is in the denominator of the equation to find the molar mass once the ideal gas equation is manipulated. So i think that with the formation of dimers the molar mass would increase?
How does on determine a molecular formula from the empirical formula?
molar mass over grams of elementThe above answer is somewhat correct. In order to find the molecular formula when given the empirical formula, you must first find the molar mass of the empirical formula.MOLAR MASS# atoms element A x Atomic Mass element A (Periodic Table) = mass A# atoms element B x atomic mass element B (periodic table) = mass B... etc.Add up all of the mass values found above and you have the molar mass.Then, after you have found the empirical formula's molar mass, you divide the molar mass of the molecular formula by the empirical formula's molar mass (solving for n).MOLECULAR FORMULA EQUATION: N (Empirical formula) (read as N times empirical formula) where:N = Molar mass substance---- Molar Mass emp. form.
Which is the molar mass of the element Calcium?
To find the molar mass of Calcium, you have to multiply Calcium's atomic number by moles. The equation is: (6.022x10^23)x 40.08= 2.4136176x10^25
How can one determine the molar mass of a substance by considering its density, pressure, and temperature?
To determine the molar mass of a substance using density, pressure, and temperature, one can use the ideal gas law equation, PV nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature. By rearranging the equation to solve for molar mass (M), M (mRT)/(PV), where m is the mass of the substance, one can calculate the molar mass by plugging in the given values for density, pressure, and temperature.
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
What is mass Stoichiometry?
The number of moles in the equation of B DIVIDED BY the number of moles in the equation of A ANSWER TIMES the molar mass of B OVER 1. A is the the known compound, B is the one your trying to find out.
