To find the grams of sodium acetate used, we first need to determine the molecular weight of sodium acetate. The chemical formula for sodium acetate is NaC2H3O2, and its molecular weight is 82.03 g/mol.
To calculate the grams of sodium acetate used by the student, we can use the following formula:
grams = moles x molecular weight
So,
grams of sodium acetate = 0.100 mol x 82.03 g/mol = 8.203 g
Therefore, the student used 8.203 grams of sodium acetate.
To find the number of molecules of sodium acetate used, we can use Avogadro's number, which is 6.022 x 10^23 molecules/mol.
The number of molecules of sodium acetate used can be calculated using the following formula:
number of molecules = moles x Avogadro's number
So,
number of molecules of sodium acetate = 0.100 mol x 6.022 x 10^23 molecules/mol = 6.022 x 10^22 molecules
Therefore, the student used 6.022 x 10^22 molecules of sodium acetate.
The molar mass of ammonium acetate is 77.083 g/mol. A student uses 0.100 mol of ammonium acetate in a chemical reaction.
