What is the molar mass for the compound CaBr2?
The molar mass of CaBr2 (calcium bromide) is calculated by adding the atomic masses of calcium (Ca) and two bromine (Br) atoms. The atomic mass of calcium is approximately 40.08 g/mol and bromine is approximately 79.90 g/mol. Therefore, the molar mass of CaBr2 is 40.08 + (2 * 79.90) = 199.88 g/mol.
Convert 14 moles of caBr2 to grams?
To convert 14 moles of CaBr2 to grams, you need to use the molar mass of CaBr2, which is 200.11 g/mol. Multiply the number of moles by the molar mass: 14 moles x 200.11 g/mol = 2,801.54 grams of CaBr2.
What is the molar mass calcium bromide?
The molar mass of calcium bromide (CaBr2) is approximately 199.89 g/mol.
How many grams of CaBr2 are there in 0.31moles of CaBr2?
To find the number of grams of CaBr2 in 0.31 moles, you first calculate the molar mass of CaBr2, which is approximately 199.89 g/mol. Then, you can multiply the number of moles (0.31 moles) by the molar mass to find the grams: 0.31 moles x 199.89 g/mol = 61.97 grams of CaBr2.
How do you find the percent of oxygen by mass in a compound?
To find the percent of oxygen by mass in a compound, you need to know the molar mass of the compound and the molar mass of oxygen. Divide the molar mass of oxygen by the molar mass of the compound and multiply by 100 to get the percentage.

What is the molar mass calcium bromide?
The molar mass of calcium bromide (CaBr2) is approximately 199.89 g/mol.
How many moles of CaBr are in 5.0 grams of CaBr2?
To find the number of moles of CaBr2 in 5.0 grams, you first need to calculate the molar mass of CaBr2. The molar mass of CaBr2 is 200.8 g/mol. Divide the given mass by the molar mass to find the number of moles: 5.0 g / 200.8 g/mol = 0.025 moles of CaBr2. Since there is one mole of CaBr2 for every two moles of CaBr, you have half of that amount in moles of CaBr: 0.025 moles / 2 = 0.0125 moles of CaBr.
How many grams of CaBr2 are there in 0.31moles of CaBr2?
To find the number of grams of CaBr2 in 0.31 moles, you first calculate the molar mass of CaBr2, which is approximately 199.89 g/mol. Then, you can multiply the number of moles (0.31 moles) by the molar mass to find the grams: 0.31 moles x 199.89 g/mol = 61.97 grams of CaBr2.
How do you find the percent of oxygen by mass in a compound?
To find the percent of oxygen by mass in a compound, you need to know the molar mass of the compound and the molar mass of oxygen. Divide the molar mass of oxygen by the molar mass of the compound and multiply by 100 to get the percentage.
Does the molar mass of a compound change depending on the weight of the compound?
Molar mass depend on the ,mass,type and number of atoms in molecules of compound.
How much of a 4.45 M CaBr2 solution can be prepared if one has 79.6 g of CaBr2 available?
To calculate the amount of solution that can be prepared, first calculate the molar mass of CaBr2 (ca. 200.11 g/mol). Then, divide the given mass of CaBr2 by its molar mass to get moles (ca. 0.398 mol). Finally, use the molarity formula (Molarity = moles of solute/volume of solution in liters) to determine the volume that can be prepared.

How are chemicals related to atomic mass?
The molar mass of a compound is the sum of atomic weights of the contained elements in the molecule.The expression atomic weight is correct for elements; for isotopes is correct atomic mass.
Which statement shows how to correctly convert from the mass of a compound in grams to the amount of that compound in moles?
To convert from the mass of a compound in grams to the amount of that compound in moles, you need to divide the mass of the compound in grams by its molar mass (which is found on the periodic table). This will give you the number of moles of the compound. The formula to use is: moles = mass (g) / molar mass.
How do you find theoretical percent of water?
To find the theoretical percent of water in a compound, you need to determine the molar mass of the compound and the molar mass of water. Then, divide the molar mass of water by the molar mass of the compound and multiply by 100 to get the percentage.
