The molarity of a solution is the number of moles of a substance divided by the volume in liters prepared.
, where n is number of moles and V is the volume in liters.
In order to calculate the mass of solute we need to convert the volume and molarity to moles
Now that we have moles we use the relative formula mass of NaCO₃, We have 1 Na atom, 1 C atom and 3 O atoms, thus
Answer:
0.1056 mole
Explanation:
As Sally knows that the charge on the metal ion is n = +2
In that compartment
The volume of the taken in that compartment = 6.380 mL
So, the number of moles of
= 52.82 m mol
= 0.05280 mol
But n = 2
Therefore, moles of = 2 x moles of
= 2 x 0.05282
= 0.1056 mole
