To determine the number of grams of bromine that will completely react with 5.0 g of pent-1-ene, we need to determine the molar mass of pent-1-ene and the molar mass of bromine.
The molar mass of pent-1-ene can be calculated by summing the atomic masses of its constituent elements. The molecular formula of pent-1-ene is C5H10, so the molar mass of pent-1-ene is:
(5 * atomic mass of carbon) + (10 * atomic mass of hydrogen)
= (5 * 12.01 g/mol) + (10 * 1.01 g/mol)
= 60.05 g/mol + 10.10 g/mol
= 70.15 g/mol
The reaction between pent-1-ene and bromine is a 1:1 ratio, meaning that for every mole of pent-1-ene, one mole of bromine is required.
To determine the number of moles of pent-1-ene, we can use the formula:
moles = mass / molar mass
moles of pent-1-ene = 5.0 g / 70.15 g/mol
= 0.0712 mol
Since the reaction is a 1:1 ratio, the number of moles of bromine required will also be 0.0712 mol.
Finally, to determine the mass of bromine required, we can use the formula:
mass = moles * molar mass
mass of bromine = 0.0712 mol * molar mass of bromine
The molar mass of bromine is 79.90 g/mol.
mass of bromine = 0.0712 mol * 79.90 g/mol
= 5.68 g
Therefore, the number of grams of bromine that will completely react with 5.0 g of pent-1-ene is 5.68 grams.
The molar mass of pent-1-ene can be calculated by summing the atomic masses of its constituent elements. The molecular formula of pent-1-ene is C5H10, so the molar mass of pent-1-ene is:
(5 * atomic mass of carbon) + (10 * atomic mass of hydrogen)
= (5 * 12.01 g/mol) + (10 * 1.01 g/mol)
= 60.05 g/mol + 10.10 g/mol
= 70.15 g/mol
The reaction between pent-1-ene and bromine is a 1:1 ratio, meaning that for every mole of pent-1-ene, one mole of bromine is required.
To determine the number of moles of pent-1-ene, we can use the formula:
moles = mass / molar mass
moles of pent-1-ene = 5.0 g / 70.15 g/mol
= 0.0712 mol
Since the reaction is a 1:1 ratio, the number of moles of bromine required will also be 0.0712 mol.
Finally, to determine the mass of bromine required, we can use the formula:
mass = moles * molar mass
mass of bromine = 0.0712 mol * molar mass of bromine
The molar mass of bromine is 79.90 g/mol.
mass of bromine = 0.0712 mol * 79.90 g/mol
= 5.68 g
Therefore, the number of grams of bromine that will completely react with 5.0 g of pent-1-ene is 5.68 grams.
