How many grams of lithium hydroxide are produced when 492 grams of water reacts with lithium nitride

Mass = 653.84 g

Explanation:

Given dа ta:

Mass of water = 492 g

Mass of lithium hydroxide = ?

Solution:

Chemical equation:

Li₃N + 3H₂O → 3LiOH + NH₃

First of all we will calculate the number of moles of water.

Number of moles of water:

Number of moles = mass / molar mass

Number of moles = 492 g / 18 g/mol

Number of moles = 27.3 mol

Now we will compare the moles of water with lithium hydroxide.

H₂O : LiOH

3 : 3

27.3 : 27.3

Mass of lithium hydroxide:

Mass = number of moles * molar mass

Mass = 27.3 mol * 23.95 g/mol

Mass = 653.84 g
