A = εmCl The basic idea here is to use a graph plotting Absorbance vs. Concentration of known solutions. Once you have that you can compare the absorbance value of an unknown sample to figure out its concentration. You will be applying Beer's law to calculate the concentration. The equation for Beer's law is: A = εmCl (A=absorbance, εm = molar extinction coefficient ...
- What is the molar mass of NaCl (table salt)? - Socratic"58.44277 g/mol" Sodium chloride, also known as table salt, is an ionic compound composed of sodium cations, "Na"^(+), and chloride anions, "Cl"^(-) that has the formula unit "NaCl". The molar mass of an anionic compound tells you what the mass of one mole of formula units of that respective compound is. You know that sodium chloride's formula unit contains one sodium atom one chlorine atom ...
- Electronic configuration of bromine - SocraticUse a chart such as the one below to fill the subshells in order of the diagonal lines. #s# subshells hold a maximum of 2 electrons, #p# subshells hold 6 electrons, #d# subshells hold 10 electrons, and #d# subshells hold 14 electrons.
- What is 35% as a fraction in the simplest form? - Socratic7/20 35% = 35/100 Divide top and bottom by 5: 35/100 * (1/5)/(1/5) = 7/20. What would be the result of dividing the diameter of a circle into 8 equal parts (expressed as a...
- Combinations and Permutations - Statistics - SocraticIn poker, a 5-card hand is called two pair if there are two cards of one rank, two cards of another rank, and a fifth card of a third order of the cards doesn't matter (so, example, QQ668 and 68QQ6 are the same).
