Question: How many milliequivalents per liter (mEq/L) are 700 mg KCL in 900 mL solution? Equivalent Per Litre of Potassium Chloride Solution: Equivalent mass is defined as the number of parts by mass of a substance that can combine/displace 1.008 parts by mass of hydrog...
A quantity commonly used to express the concentration of a solution is called the molarity of the solution. It gives the number of moles n of solute that dissolves in a volume V of the solution in liters (L), or in formula form: ...
1. The density of mercury is 13.6 g/mL. What is its density in lbs/L? (Hint: 1 lb = 0.454 kg). 2. If you are driving at a speed of 55.0 miles per hour, then what is your speed in meters per second? (H How many moles of chloroethylen...
If 3.50 mL of vinegar needs 45.0 mL of 0.150 M NaOH to reach the equivalence point in a titration, how many moles of NaOH were used in the titration? How many milliliters of 0.115 M HCl are needed to titrate each of the following solutions to t...
Equivalents per liter is therefore a unit of concentration, but the most commonly seen unit throughout chemistry is the mEq/L.Examples of mEq/L 1. How many mEq of potassium are there in 750 mL of solution that has a K+ concentration of 58.65 mg/L? (Note: The molar mass of potassium...
Divide the number of moles by the volume of solution in liters (L). If, for instance, the solution is 1.5 L — 1.32 ÷ 1.5 = 0.88. This is the solution's particle concentration, measured in molarity (M), or moles per liter.Cite This Article MLA Menezes, Ryan. "How To Calculate ...

*TSH=thyroid-stimulating hormone; LDL=low-density lipoprotein; HDL=high-density lipoprotein; CRP=C-reactive protein; mg/dL=milligrams per deciliter; µmol/L=micromoles per liter; mIU/L=milli-international units per liter; mg/L=milligrams per liter; ng/mL=nanograms per milliliter; mmHg=mill...
moles of water in one drop = 0.002775 moles Using Avogrado's Number Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of water per mole of water. So, next we calculate how many molecules there...
First, determine how many moles are present in 3 grams of KCl. Start by looking up the number of grams per mole of potassium and chlorine on aperiodic table. Then add them together to get the grams per mole for KCl. K = 39.1 g/mol Cl = 35.5 g/mol KCl = 39.1 + 35.5 = 74.6 g/...
