What else can I help you with?
What is the mass of PbBr2?
I assume you mean the molecular mass. Its molecular mass is 367.01g/mol
What is the relationship between the molar mass of a gas and its density?
The relationship between the molar mass of a gas and its density is that as the molar mass of a gas increases, its density also increases. This means that gases with higher molar masses will be denser than gases with lower molar masses.
How can you compare the rates of effusion of two gases in a mixture?
The rate of effusion of gases is inversely proportional to the square root of their molar masses. By comparing the molar masses of the two gases, you can determine which gas effuses faster. The gas with the lower molar mass will effuse more quickly.
How do you calculate the molar mass of a compound?
To calculate the molar mass of a compound, you add up the atomic masses of all the elements in the compound as indicated by its chemical formula. The atomic masses can be found on the periodic table.
What do the molar masses of any two elements contain the same number of what?
Atoms have atomic weight not molar mass. Any atom-gram has 6,022 141 29(27)×1023 (this is the number of Avogadro) atoms.
What is the mass of PbBr2?
I assume you mean the molecular mass. Its molecular mass is 367.01g/mol
What is the molar solubility of PbBr2 in water?
The molar solubility of PbBr2 in water is approximately 1.6 x 10^-3 mol/L at 25°C. This means that at this temperature, 1.6 x 10^-3 moles of PbBr2 will dissolve in one liter of water.
If you know the molar masses of the reactants in a chemical reaction can you determine the molar masses of the products?
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
What is the relationship between the molar mass of a gas and its density?
The relationship between the molar mass of a gas and its density is that as the molar mass of a gas increases, its density also increases. This means that gases with higher molar masses will be denser than gases with lower molar masses.
Is defined as the sum of the atomic masses in the molecule?
This is the molar mass.
How can you compare the rates of effusion of two gases in a mixture?
The rate of effusion of gases is inversely proportional to the square root of their molar masses. By comparing the molar masses of the two gases, you can determine which gas effuses faster. The gas with the lower molar mass will effuse more quickly.
How do you calculate the molar mass of a compound?
To calculate the molar mass of a compound, you add up the atomic masses of all the elements in the compound as indicated by its chemical formula. The atomic masses can be found on the periodic table.
What two pieces of information are needed to determine the ratio of elements in a compound?
The chemical formula of the compound (e.g., H2O for water) and the molar masses of the elements present in the compound are needed to determine the ratio of elements. The molar masses are required to calculate the molar ratios of the elements in the compound.
For PbBr2 Ksp equals 6.3 x 10 -6 at 25C what is the solubility of PbBr2 at this temperature?
1.2x10-2
How do you calculate the masses of carbon dioxide hydrogen and oxyen at STP?
If you know moles of each use their molar masses to convert to mass.
LiCl plus PbBr2 is?
PbBr2 is only slightly soluble in water, but more so than PbCl2, so if you had to write the equation it would be2LiCl(aq) + PbBr2(aq) ==> 2LiBr(aq) + PbCl2(s)
What do the molar masses of any two elements contain the same number of what?
Atoms have atomic weight not molar mass. Any atom-gram has 6,022 141 29(27)×1023 (this is the number of Avogadro) atoms.
