Question

How many moles of sodium can be produced if 378.3 grams of sodium azide is used

Answer 1

Answer:

5.82 moles of sodium will produced.

Explanation:

Given data:

Mass of sodium azide = 378.3 g

Moles of sodium produced = ?

Solution:

Chemical equation:

2NaN₃   →   2Na  + 3N₂

Moles of sodium azide:

Number of moles = mass/ molar mass

Number of moles = 378.3 g/ 65 g/mol

Number of moles = 5.82 mol

Now we will compare the moles of sodium azide and sodium.

                          NaN₃      :       Na    

                             2          :         2

                            5.82      :        5.82
