How many molecules of bromine are present in 120 grams of bromine gas?
To determine the number of molecules in 120 grams of bromine gas, you first need to calculate the moles of bromine using its molar mass (molar mass of Br2 = 159.808 g/mol). Then, use Avogadro's number (6.022 x 10^23) to find the number of molecules in that many moles of bromine gas.
How many grams in 10 ml of bromine?
The density of bromine is 3.12 g/ml, therefore 10 ml of bromine would weigh 31.2 grams.
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).
How many grams are in one mole of Bromine trifluoride?
The molar mass of Bromine trifluoride is approximately 126.893 g/mol. Therefore, one mole of Bromine trifluoride contains 126.893 grams.
How many grams of sodium carbonate contain 1.773 x 1017 carbon atoms?
To find how many grams of sodium carbonate contain 1.773 x 10^17 carbon atoms, you need to consider the molar ratio. Sodium carbonate (Na2CO3) has 1 carbon atom per molecule. Calculate the molar mass of Na2CO3, then use Avogadro's number to convert the number of carbon atoms to moles, and finally to grams.
How many moles of bromine atoms are in 2.60x102 grams of bromine?
2,60x102 grams of bromine (Br) is equal to 1,627 moles Br2.
How many hydrogen atoms are in 1.25 grams of CH4?
1,25 grams of CH4 contain 0,156696.10e23 atoms.
How many grams of hafnium contains the same number of atoms as 10.7nanograms of bromine?
24,163 ng
How many oxygen atoms are there in 3.45 grams of H2O?
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
Is The chemical formula CuBr2 that this compound is composed of 1 gram of copper and 2 grams of bromine?
No, the chemical formula CuBr2 indicates one atom of copper bonding with two atoms of bromine. This means that the molar mass of CuBr2 is not equal to the sum of the molar masses of copper and bromine individually.
How many grams are in 6.355 x 1010 atoms of iron?
6.355 x 10e10 atoms of iron contain 58,93.e-13 grams
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 molecules of bromine are present in 120 grams of bromine gas?
To determine the number of molecules in 120 grams of bromine gas, you first need to calculate the moles of bromine using its molar mass (molar mass of Br2 = 159.808 g/mol). Then, use Avogadro's number (6.022 x 10^23) to find the number of molecules in that many moles of bromine gas.
What the cost of Bromine?
the answer to this question is 4.9$ for 100 grams of pure bromine.
How many grams in 10 ml of bromine?
The density of bromine is 3.12 g/ml, therefore 10 ml of bromine would weigh 31.2 grams.
How many grams atoms are in 100 of sulfur?
The molar mass of sulfur is approximately 32 grams per mole. Therefore, 100 grams of sulfur would contain approximately 3 moles of sulfur atoms (100 grams / 32 grams/mole). To find the number of atoms, you would then multiply the number of moles by Avogadro's number (6.022 x 10^23 atoms/mole) to get the total number of sulfur atoms in 100 grams.
How many atoms does g of sulfur contain?
Just about 6.022 X 1023 atoms of sulfur. Sulfur is 32.07 grams per mole.
