The molar mass of argon is 40 gmol. What is the molar mass of a gas if it effuses at 0.91 times the speed of argon gas?
graham's law (Rate 1 / rate 2) ^2 = MM2 / MM1 (Rate x / rate Ar) ^2 = MM Ar / MM x (.907)^2 = 39.9481 / MMx MMx = 39.9481 / 0.8226 Molar mass of unknown gas = 48.56 g / mole
What is the molar mass of the sugar called glucose?
The molar mass of glucose is 180,16 g.
Calculate the ratio of effusion rates for Ar and Kr?
The ratio of effusion rates for two gases is given by the square root of the inverse ratio of their molar masses. The molar mass of Ar is approximately 40 g/mol, and for Kr it is approximately 84 g/mol. So, the ratio of effusion rates for Ar and Kr is √(84/40) ≈ 1.3.
What is the molar mass of PbSO4?
The molar mass of PbSO4 (lead(II) sulfate) is approximately 303.3 g/mol. This can be calculated by adding the molar masses of each element in the compound: lead (Pb) has a molar mass of 207.2 g/mol, sulfur (S) has a molar mass of 32.1 g/mol, and oxygen (O) has a molar mass of 16.0 g/mol.
What is the molar mass of Te?
The molar mass of H2Te = 129.61588 g/mol
What is the molar mass of argon?
The molar mass of argon (Ar) is approximately 39.95 grams per mole.
The rate of effusion of Argon was measured to be 0.218mols at a certain temperature Calculate the rate of effusion of helium gas (Molar mass of Ar=40,Molar mass of Helium =4)?

What is the AR or MR value of Co2 and NA2CO3?
The AR (atomic mass) of CO2 (carbon dioxide) is 44 g/mol. The MR (molar mass) of Na2CO3 (sodium carbonate) is 106 g/mol.
How many moles are in 11.8g Ar?
The answer is 0,0719 mol.
How many molecules are in 11.2 g Ar?
To find the number of molecules in 11.2 g of Ar, you need to use Avogadro's number and the molar mass of Ar. First, find the number of moles in 11.2 g using the molar mass of Ar (39.95 g/mol). Then, convert moles to molecules by multiplying by Avogadro's number (6.022 x 10^23 molecules/mol).
The molar mass of argon is 40 gmol. What is the molar mass of a gas if it effuses at 0.91 times the speed of argon gas?
graham's law (Rate 1 / rate 2) ^2 = MM2 / MM1 (Rate x / rate Ar) ^2 = MM Ar / MM x (.907)^2 = 39.9481 / MMx MMx = 39.9481 / 0.8226 Molar mass of unknown gas = 48.56 g / mole
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 the molar mass of sulfur?
The molar mass of sulfur is approximately 32.06 grams per mole.
What is the mass in grams of one mole of argon?
The molar mass of Argon (Ar) is approximately 39.95 grams. Therefore, one mole of Argon would have a mass of 39.95 grams.
What is the molar mass of the sugar called glucose?
The molar mass of glucose is 180,16 g.
How many moles are in 0.476 grams of bromine?
To find the number of moles in 0.476 grams of bromine, you first need to determine the molar mass of bromine, which is approximately 79.904 g/mol. Then, you can use the formula: moles = mass (g) / molar mass (g/mol). Therefore, in this case, 0.476 grams of bromine is equivalent to 0.006 moles.
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)
