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.

<h2>
So, there are 17.85 moles in 1.5 kg of Sodium bicarbonate.</h2>
Let the solution cool down really slowly, don’t disturb it at all.
the water wants to give the electricity to you because it doesn't want any more electrons it throws them away and gives them to your body
I’m assuming you mean 5g of magnesium :)
