What is the percent of lead in lead IV oxide Or how do i calculate it?
86.62(8)%The molar masses of the constituent elements must be known.M(Pb) = 2.072(1) x 102 gmol-1M(O) = 1.59994(3) x 10 gmol-1From these and their respective molar ratios in the compound, the total molar mass of the compound must be calculated.M(PbO2) = M(Pb) + 2M(O)M(PbO2) = (2.072 x 10 gmol-1 + 2(1.59994 gmol-1)) x 10M(PbO2) = 2.392(1) x 102 gmol-1From the molar mass of the element in question and its ratio, and the compound, their total masses present in one mole of compound must be calculated.m = nMm(Pb) = 1 mol x 2.072 x 102 gmol-1m(Pb) = 2.072(1) x 102 gm(PbO2) = 1 mol x 2.392(1) x 102 g (always 1 mole)m(PbO2) = 2.392(1) x 102 gFrom these, the percentage of the element in question present in the compound can be calculated.m(Pb) x 100%/m(PbO2) = 2.072 g x 100%/2.392 gm(Pb) x 100%/m(PbO2) = 86.62(8)%
What is the mass of 1 mol of rubidium?
According to the periodic table, the atomic mass of rubidium, Rb is 85.5. This is numerically equal to the molar mass in g/mol. Therefore the mass of 1 mol of Rb is 85.5g.Mass of 1 mol means the molar mass of the element. Molar mass of Rubidium is 85.47 gmol-1. Rb is in the 1st group.
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

A compound with the empirical formula SN was found in a subsequent experiment to have a molar mass of 184.32 gmol. What is the molecular formula of the compound?
The empirical formula of SN has a formula unit mass of the sum of the gram atomic masses of nitrogen and sulfur, i.e., about 46.0667. The gram molecular mass given in the problem divided by this formula unit mass is about 4. Therefore, the molecular formula is S4N4.
How are molarity and molar mass related for a compound?
The molar mass of a substance is measured in grams per mole written as gmol-1. It is worked out using the Mole formula by dividing mass in grams by the amount in moles.
If an unknown hydrate MgCl2 and bullxH2O has a molecular mass of 203.30 gmol what is the numeric value of x in the formula?
This formula is for magnesium chloride hexahydrate: MgCl2.6H2O.
A compound formed of 0.059 mol hydrogen and 0.94 mol oxygen has a molecular mass of 34.0 g per mole. What is the molecular formula of this compound?
There is most likely a mistake in this question, as the mole ratio of O to H here is 0.94/0.059 = 16 : 1 which is not likely in nature, and it would also not have a molar mass of 34.0 g/mol. The answer is H2O2 (hydrogen peroxide) which has a molar mass of 34 g/mole, but the mole ratio of O to H is 1:1.
