How many liters of 2.5-M KOH solution can be prepared from 112g of KOH?

Volume in litter = 0.8 L

Explanation:

Given dа ta:

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
