Hello!
We have the following data:
MM (Molar mass of Na2CO3)
Na = 2*23 = 46 u
C = 1*12 = 12 u
O = 3*16 = 48 u
----------------------
MM (Molar mass of Na2CO3) = 46+12+48 = 106 g/mol
n (mol number) = 1 mol
m1 (mass of the solute) = ?
So if we have the dissolution in a liter (m2 - mass of solvent), that is 1000g , then the total mass of the solution (m) will be:
<span>Now, let's find the percentage in mass (% m / m), let's see:
</span>
Answer: B) 9.6
I Hope this helps, greetings ... DexteR!
