How many 07L is to how many cL?
1 L = 100 cL so 07 L = 7 L = 7*100 cL = 700 cL.
Calculate the sodium ion concentration when 40.0 mL of 2.5 M sodium carbonate is added to 30.0 mL of 1.0 M sodium bicarbonate?
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
