Answer:
1.31M
Explanation:
Based on the reaction, 1 mole of Zn produce 1 mole of ZnCl₂. As the reaction occurs completely, the moles of Zn added = Moles of ZnCl₂ produced. To find molarity we need the moles of ZnCl₂ and the volume of the solution in liters:
Moles Zn = Moles ZnCl₂ -Molar mass Zn: 65.38g/mol-:
15g * (1mol / 65.38g) = 0.23 moles of ZnCl₂
Volume in Liters:
175mL * (1L / 1000mL) = 0.175L
The molarity is:
0.23moles / 0.175L
1.31M
