What amount of substance corresponds to 810 g of hydrogen bromide (HBr)?
| July 4, 2021 | education
The mass of hydrogen bromide is 810 g.
Determine the amount of substance of a given hydrogen bromide. For this we use the following formula.
n = m / M.
Where n is the amount of substance.
M is the molar mass of the substance.
m is the mass of the substance.
Determine the molar mass of hydrogen bromide using the table of chemical elements.
M (HBr) = 79.9 + 1 = 80.9 g / mol.
Next, we substitute the known data into this formula. We write down the solution.
n = 810 g / 80.9 g / mol = 10.01 mol.
Therefore, 10.01 mol of hydrogen bromide corresponds to 810 grams of the substance.
Answer: 10.01 mol.
