Answer:
5.42 mol
Explanation:
To find moles, divide the given mass by the compounds molar mass. To find the molar mass of the compound, add of the masses of each individual component:
Molar mass of NaNCO3 = Na + N + C + (O x 3)
Molar mass of NaNCO3 = 23 + 14 + 12 + (16 x 3)
Molar mass of NaNCO3 = 97 g/mol
Moles = mass / molar mass
Moles = 526 g / 97 g/mol
Moles = 5.42 mol
