Question

write three method to calculate mole​

Answer 1

Answer:

Step 1: Write the mathematical equation to calculate moles of calcium carbonate: n(mol) = m(g) ÷ M(g mol-1)

Step 2: Calculate the mass of calcium carbonate in the sample in kilograms (kg). ...

Step 3: Convert the mass of calcium carbonate in kilograms (kg) to mass in grams (g) m(CaCO3) in grams = m(CaCO3) in kg × 1000 g/kg.

Answer 2

Answer:

Step 1: Write the mathematical equation to calculate moles of calcium carbonate: n(mol) = m(g) ÷ M(g mol-1)

Step 2: Calculate the mass of calcium carbonate in the sample in kilograms (kg). ...

Step 3: Convert the mass of calcium carbonate in kilograms (kg) to mass in grams (g) m(CaCO3) in grams = m(CaCO3) in kg
