Apotassium chloride solution that also contains 5% (m/v) dextrose is administered intravenously to treat some forms of malnutrition. the potassium ion concentration in this solution is 35 meq/l. calculate the potassium ion concentration in units of mol/l.

Answer : The potassium ion concentration in units of mol/L is,

Explanation :

As we are given that the concentration of potassium ion in the solution is 35 meq/L. Now we have to determine the potassium ion concentration in units of mol/L.

First we have to convert meq/L to eq/L.

Conversion used :

1 meq/L = 10⁻³ eq/L

As, 1 meq/L concentration of potassium ion = 10⁻³ eq/L

So, 35 meq/L concentration of potassium ion = 35 × 10⁻³ eq/L

As we know that:

where,

= n- factor or valency of ion

for potassium ion = 1

So, the concentration of potassium ion =

Therefore, the potassium ion concentration in units of mol/L is,

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

ok whats the question if not i cannot you i need question and need a thing to answer
