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

Mass = 653.84 g

Explanation:

Given data:

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

answer: h+ its less than oh
