How many moles of calcium chloride are needed to produce 6.50 moles of sodium chloride?

This question appear incomplete

Explanation:

This question appear incomplete because an equation to show the production of sodium chloride from calcium chloride should have been illustrated. However, if the balanced chemical equation showing sodium chloride (NaCl) been a product of a reaction involving calcium chloride (CaCl₂) as a reactant (shown below) is to be used, then we start by writing a complete balanced chemical equation

CaCl₂ + Na₂CO₃  ⇒   CaCO₃ + 2NaCl

From the equation above, it can be deduced that 1 mole of CaCl₂ is required to produce 2 moles of NaCl, thus how many moles of CaCl₂ will be required to produce 6.5 moles of NaCl.

1 mole of CaCl₂ = 2 moles of NaCl

? moles of CaCl₂ = 6.5 moles of NaCl

cross multiply

? moles of CaCl₂ = 6.5 × 1/2

? moles of CaCl₂ = 3.25 moles of CaCl₂

3.25 moles of CaCl₂ will be needed to produce 6.5 moles of NaCl
