Question

How many grams of ammonium chloride (NH4Cl) do you have if you have 0.436 moles?

Answer 1

23.33 g

Step-by-step explanation:

molar mass is the mass of 1 mol of atom/compound

molar mass of a compound can be calculated by taking the sum of the products of the molar mass of each element by the number of molecules of that element in the compound

molar mass of NH₄Cl

molar mass of N - 14 g/mol

molar mass of H - 1 g/mol

molar mass of Cl - 35.5 g/mol

molar mass of NH₄Cl - (14 g/mol x 1) + (1 g/mol x 4) + (35.5 g/mol x 1) = 53.5 g/mol

therefore mass of 1 mol of NH₄Cl - 53.5 g

mass of 0.436 mol = 53.5 g/mol x 0.436 mol = 23.33 g

mass of NH₄Cl is 23.33 g

Answer 2

0.436 moles of ammonium chloride (NH4Cl) has a mass of 23.3 grams

Step-by-step explanation:

Step 1: Data given

Number of moles of NH4Cl = 0.436 moles

Molar mass of NH4Cl = 53.49 g/mol

Step 2: Calculate mass of ammonium chloride

Mass = moles * molar mass

Mass NH4Cl = moles NH4Cl * molar mass NH4Cl

Mass NH4Cl = 0.436 moles * 53.49 g/mol

Mass NH4Cl = 23.3 grams

0.436 moles of ammonium chloride (NH4Cl) has a mass of 23.3 grams
