Question

How many moles of sodium bicarbonate are in 1.50 kg of the compound?

Answer 1

n=17.85 moles

Step-by-step explanation:

Given mass is, m = 1.5 kg = 1500 g

The molar mass of sodium bicarbonate is, M = 84.007 g/mol

We need to find the no of moles in 1.5 kg of Sodium bicarbonate . We know that, no of moles is equal to given mass divided by molar mass.

`n=(m)/(M)\\\\n=(1500)/(84.007 )\\\\n=17.85`

So, there are 17.85 moles in 1.5 kg of Sodium bicarbonate.
