Answer:

n=17.85 moles

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.

[tex]n=\dfrac{m}{M}\\\\n=\dfrac{1500}{84.007 }\\\\n=17.85[/tex]

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