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,

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
