Calculate the molecular mass of hydrogen bromine?
The atomic mass of hydrogen is 1u. Atomic mass of bromine is 80u. Therefore, the molar mass of hydrogen bromide is 1+80=81u.
What is the atomic mass of AgBr?
The atomic mass of AgBr, which is a compound made up of silver (Ag) and bromine (Br) is the sum of the atomic masses of silver and bromine. Silver has an atomic mass of approximately 107.87 g/mol, while bromine has an atomic mass of approximately 79.904 g/mol. Therefore, the atomic mass of AgBr is approximately 107.87 + 79.904 = 187.774 g/mol.
What is the molar mass for tribromine oxide?
The molar mass of tribromine oxide (Br3O) can be calculated by adding up the atomic masses of its constituent atoms. The molar mass of bromine (Br) is approximately 79.90 g/mol, and the molar mass of oxygen (O) is approximately 16.00 g/mol. Therefore, the molar mass of tribromine oxide is approximately 249.70 g/mol.
Can one use the average mass of elemental bromine for the atomic mass of bromine?
Yes, that is what is used. Bromine is I think ~51:49 ratio of Br79 and Br81. Therefore it is somewhere in between (79.9g/mol)
How many grams of Br are in 595 g of CaBr2?
To find the grams of bromine (Br) in 595 g of calcium bromide (CaBr2), first determine the molar mass of CaBr2. The molar mass is approximately 40.08 g/mol for Ca and 79.90 g/mol for Br, giving a total of about 199.89 g/mol for CaBr2. Since there are two bromine atoms in each formula unit, the mass of bromine in CaBr2 is about 159.80 g (2 × 79.90 g). Thus, the mass of Br in 595 g of CaBr2 can be calculated as follows: (159.80 g Br / 199.89 g CaBr2) × 595 g CaBr2 ≈ 477.23 g of Br.
Aluminum will react with bromine to form aluminum bromide Al2Br6 What mass of bromine g is needed to form 1.42 mol of Al2Br6?
The gram formula unit or molar mass for aluminum bromide is 533.38.* Therefore, 1.42 moles has a mass of 757.4 grams. The mass of 6 moles of bromine atoms is 479.42. Therefore, the mass fraction of bromine in aluminum bromide is 479.42/757.4 or 0.633, and the mass in grams of bromine required to form 1.42 moles of aluminum bromide is 0.633 X 757.4 or 479 grams, to the justified number of significant digits (limited by the precision given for the number of moles.) ___________________ *This is equal to the sum of (2 times the gram atomic mass of aluminum) and (6 times the gram atomic mass of bromine).
What is the mass of bromine in 50.0g potassium bromide?
The chemical formula of potassium bromide is KBr, showing that each formula unit contains equal numbers of potassium and bromine atoms. The gram atomic masses of potassium and bromine are 39.0983 and 70.904 respectively. Therefore, the mass fraction of bromine in KBr is 70.904/(70.904 + 39.0983) or about 0.644568. 50.0 g of potassium bromide therefore contains 32.2 g of bromine, to the justified number of significant digits.
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.
How many moles of bromine gas are in 37.7 grams?
To determine the number of moles of bromine gas in 37.7 grams, you need to divide the given mass by the molar mass of bromine. The molar mass of bromine is approximately 79.904 g/mol. So, 37.7 grams of bromine is equal to 0.471 moles (37.7 g ÷ 79.904 g/mol).
What is the percent composition of bromine in the compound NaBr?
Bromine has an atomic mass of 79.904 g/mol, while the molar mass of NaBr is 102.89 g/mol. Therefore, the percent composition of bromine in NaBr is (79.904 g/mol / 102.89 g/mol) x 100 = 77.68%.
What are the molar masses of pbBr2?
The molar mass of PbBr2 is 367.008 g/mol
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.
What element is 4 times as heavy as neon atoms?
