g = moles x molar mass

How many grams are in 2.25 moles of NaBr

To determine how many grams are in 2.25 moles of NaBr (sodium bromide), you need to know its molar mass. The molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol).

To find the molar mass of NaBr, you can look up the atomic masses of each element (Na = sodium, Br = bromine) and sum them up.

The atomic mass of sodium (Na) is approximately 22.99 g/mol, and the atomic mass of bromine (Br) is approximately 79.90 g/mol.

Now, add these atomic masses together to get the molar mass of NaBr:
Molar mass of NaBr = (1 * atomic mass of Na) + (1 * atomic mass of Br)
= (1 * 22.99 g/mol) + (1 * 79.90 g/mol)
= 22.99 g/mol + 79.90 g/mol
= 102.89 g/mol

Therefore, the molar mass of NaBr is 102.89 g/mol.

To calculate the grams in 2.25 moles of NaBr, you can use the following formula:

Grams = Moles * Molar mass

Substituting the values:
Grams = 2.25 moles * 102.89 g/mol
= 231.525 g

Therefore, there are approximately 231.525 grams in 2.25 moles of NaBr.
