What is the mass of 4.89 x 1020 molecules of Br2?
1 mole Br2 = 159.808g Br2 = 6.022 x 1023 molecules Br2 4.89 x 1020 molecules Br2 x 1mol Br2/6.022 x 1023 molecules Br2 x 159.808g Br2/mol Br2 = 0.130g Br2
How many moles of atoms are in 44.0 Br2?
44.0 grams Br2 ? 44.0 grams Br2 (1 mole Br2/159.8 grams)(6.022 X 10^23/1 mole Br2)(1 mole Br2 atoms/6.022 X 10^23) = 0.275 moles of Br2 atoms
How many moles of bromine will be formed upon the complete reaction of 0.248 moles bromine trifluoride?
The complete decomposition reaction is as follows:2 BrF3 → Br2 + 3 F2 , so 2 moles BrF3 will give 1 mole Br2 , hence 0.248 mole gives 0.124 mole Br2
How many atoms are in 1.54 moles of Bromine?
1.54 (mol Br2) * 6.022*10+23 (molecule/mol Br2) * 2 (atoms Br/molecule Br2) =1.85*1024 atoms in 1.54 mole Br2
How many moles of Br2 are there in 160g?
1,012 mole of bromine for the diatomic molecule.
What is the mass in kg of 3.2L of br2?
9.92kg
Given the density of Br2 What is the molecular weight?
159.8 grams The masses (atomic mass) on the periodic table are the mass of 1 mole of the element. So all you have to do is find the atomic mass of bromine (79.9 grams) and multiply it by two since there are two atoms in the molecule.
What is the molar mass of ferric ammonium citrate?

What is the difference between the mass of a mole of oxygen and a mole of O2 molecules?
A mole of oxygen atoms has a mass of approximately 16 grams. A mole of O2 has a mass of approximately 32 grams. A mole is 6.02 x 1023 particles and as such a mole of oxygen atoms has only half the mass of a mole of oxygen molecules.
Molar is the total combined mass of a mole of a substance?

What diatomic gas with 160 amu?
The only diatomic 'GAS' with molecular mass of 160 a.m.u. (molar mass=160 g/mole)COULD be:Bromine (Br2, 159.8 a.m.u.) at a temperature above 58.8 °C (boiling point at 1 atm. pressure)At room temperature ( = at 'STP') however this is a LIQUID.(So I wonder if the questioner really was'well' informed when formulating this question, I'm curious about this!)
What equals to a mole?
