Answer:
164.3g of NaCl
Step-by-step explanation:
Based on the chemical equation:
CaCl2 + 2NaOH → 2NaCl + Ca(OH)2
where 1 mole of CaCl2 reacts with 2 moles of NaOH
To solve this question we must convert the mass of CaCl2 to moles. Using the chemical equation we can find the moles of NaCl and its mass:
Moles CaCl2 -Molar mass: 110.98g/mol-
156.0g CaCl₂ * (1mol / 110.98g) = 1.4057 moles CaCl2
Moles NaCl:
1.4057 moles CaCl2 * (2mol NaCl / 1mol CaCl2) = 2.811 moles NaCl
Mass NaCl -Molar mass: 58.44g/mol-
2.811 moles NaCl * (58.44g / mol) = 164.3g of NaCl
