M(NaCl)/{2M(NaCl)}=m(Cl₂)/M(Cl₂)
m(Cl₂)=M(Cl₂)m(NaCl)/{2M(NaCl)}
m(Cl₂)=70.90*7.5/{2*58.44}=4.55 g
m(Cl₂)=4.55 g
Answer:
Volume in litter = 0.8 L
Explanation:
Given data:
Mass of KOH = 112 g
Molarity of KOH = 2.5 M
Volume = ?
Solution:
Number of moles of KOH:
Number of moles = mass/ molar mass
Number of moles = 112 g/ 56 g/mol
Number of moles = 2 mol
Volume of KOH:
Molarity = number of moles / volume in litter
Volume in litter = number of moles / Molarity
Volume in litter = 2 mol / 2.5 mol/L
Volume in litter = 0.8 L
