The amount of protein in a sample was measured by the sample's absorbance of light at a given wavelength. Using standards, a bes
FinnZ [79.3K]

Answer:

Protein Concentration is 2.82mg/L

Explanation:

According to Beer-Lambert's Law, Absorbance is directly proportional to the concentration.

However, the concentration of a solution can be determined from a calibration curve, in which Absorbance is plotted on the y-axis and the Concentration on the x-axis.

Plotting the best line, the equation of line is used

y = mx + c

where y is absorbance = 0.150

           m is slope = 0.0163

            x is concentration

             c is intercept = 0.104

inserting the values from the question

y = mx + c

0.150 = 0.0163x + 0.104

0.0163x = 0.150 - 0.104

0.0163x = 0.046

Divide both sides by 0.0163

0.0163x/0.0163 = 0.046/0.0163

x = 2.82

Concentration of protein = 2.82 mg/L

I need help:<br>Ionic Compounds are formed from atoms that have opposite charges. True Or False?
liq [111]

It is <u>true</u> that ionic compounds are formed from atoms that have opposite charges.

<h3>What are ionic compounds?</h3>

Ionic compounds are chemical compounds made up of ions held together by electrostatic forces termed ionic bonding.

The ionic compound formed is neutrally charged but consists of positively charged ions called cations and negatively charged ions called anions.

For example, the sodium ions attract chloride ions and the chloride ion attracts sodium ions. The result is the formation of an ionic compound with cation Na+ and anion Cl– ions.

Therefore, it is true that an ionic compound is made up of positive and negative ions.

Describe a consequence of overpopulation of deer in the forest areas of the northeastern United States
muminat
If the deer population were to overpopulate then that would mean that there would not be enough room for other living things. Also, there would be less grass and plants because of the deer eating it all. Hope this helps!!!

You have 1.6 x10 21 atoms of oxygen, what is the mass of that number of atoms
iren [92.7K]

Answer: 166.023×1023

Explanation:

Mass of 6.023×1023 atoms of oxygen = gram atomic mass of oxygen.

Mass of 6.023×1023 atoms of oxygen = 16g

∴ Mass of 1 atom of oxygen =166.023×1023
