first of all, let's find the molecular formula for the two substances: Na2(CO3) and Na(HCO3).

sodium carbonate has two Na atoms in each molecule and sodium bicarbonate has only one.

now let's find the number of moles of sodium carbonate and sodium bicarbonate we have: 2.5M * .04L = .1mol

1M * .03L = .03mol

we now know that there are .2mol (.1*2) of Na in sodium carbonate because there's two sodium ions in each sodium carbonate. And we know that there's 1 Na ion in each sodium bicarbonate, so we know it's just .03 mol Na in sodium bicarbonate.

add those up: .2mol+.03mol = .23mol Na

since Molar = mol/volume, we can find the volume of the whole solution: 30mL + 40mL=70mL or .07L

.23mol/.07L is 3.29M

What is the bi in bicarbonate?

It is actually Hydrogen. Sodium Bicarbonate is properly known as Sodium Hydrogen Carbonate, and sometimes Sodium Acid Carbonate (Hydrogen makes it an acid)CompareNaHCO3 (sodium bicarbonate)Na2CO3 (sodium carbonate)Since sodium carbonate takes two sodium ions for each carbonate, and bicarbonate has only one, ratio of carbonate ions to sodium ion doubles, hence the term bicarbonate.
