The molar mass of Bromine trifluoride is approximately 126.893 g/mol. Therefore, one mole of Bromine trifluoride contains 126.893 grams.
One liter of bromine weighs approximately 3.10 kg.
To convert atoms of bromine to moles of bromine, you would need to divide the number of atoms by Avogadro's number (6.022 x 10^23). So, to get moles of bromine, you would divide the number of atoms by Avogadro's number, not multiply.
Since one mole is equal to 6.022x10^23, there are .36 moles in 2.17x10 representative particles of bromine. A mole is a measure used to make atomic calculations for density.
2Mg + Br2 ---> 2MgBr Magnesium Bromide
one mole of a substance is described as 6.02x1023 atoms of a substance so if one mole of bromide gas contains 6.02x1023 atoms then bromide gas will contain one mole. your question is a trick question as the gas is stated as containg one mole there fore it contains one mole of bromide atoms
The molar mass of Bromine trifluoride is approximately 126.893 g/mol. Therefore, one mole of Bromine trifluoride contains 126.893 grams.
One liter of bromine weighs approximately 3.10 kg.
It is 55.8 grams.
To balance the equation for the reaction between bromine (Br2) and ethanol alcohol (C2H5OH), you would need to consider the following chemical equation: C2H5OH + Br2 -> C2H4Br2 + H2O In this balanced equation, there is one mole of ethanol alcohol reacting with one mole of bromine to produce one mole of ethylene dibromide and one mole of water.
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
The molecular weight of pentane is approximately 72.15 grams per mole. So, one mole of pentane weighs 72.15 grams.
The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17 The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18 This means that one mole of NH3 weigh less than one mole of H2O
There is one mole in approximately 80 grams of bromine (Br). Therefore, in 1 gram of bromine, there would be approximately 1/80 mole, which is equal to 0.0125 moles.
1 mole of O (oxygen) weighs 15. 9996 grams. By definition, 1 mole of any element is equal to its atomic weight expressed in grams. 1 mole is equal to 6.02 x 1023 atoms of that element.
The right question should be: Does one mole of iron weigh the same as one mole of iron oxide? The answer is NO, Iron Oxide weighs more.
1 mole of all elements has 6.023 x 1023 atoms (but one mole of each element will weigh different)
