Answer:
Explanation:
Step 1: Obtain the mass of each element present in grams. Element % = mass in g = m.
Step 2: Determine the number of moles of each type of atom present. ...
Step 3: Divide the number of moles of each element by the smallest number of moles. ...
Step 4: Convert numbers to whole numbers.
The solution would be like
this for this specific problem:
Molecular formula of the
two substances: Na2(CO3) and Na(HCO3)
<span>3M * .07L = .21mol </span><span>
<span>1M * .03L
= .03mol </span></span>
<span>.42mol+.03mol = .45mol
Na </span>
30mL + 70mL=100mL or .1L
.45mol/.1L is 4.5M
So the sodium ion concentration is 4.5M. I am hoping that this
answer has satisfied your query and it will be able to help you in your
