What is the mass of Na2CO3 required to make a
Paladinen [302]

Answer:

21.2 g

Explanation:

Step 1: Given data

  • Molar concentration of the solution (C): 0.400 mol/L
  • Volume of solution (V): 500 mL (0.500 L)

Step 2: Calculate the moles of Na₂CO₃ (solute) in the solution

We will use the definition of molarity.

C = moles of solute / liters of solution

moles of solute = C × liters of solution

moles of solute = 0.400 mol/L × 0.500 L = 0.200 mol

Step 3: Calculate the mass corresponding to 0.200 moles of Na₂CO₃

The molar mass of Na₂CO₃ is 105.99 g/mol.

0.200 mol × 105.99 g/mol = 21.2 g
