It's (grams-of-Cl/total-grams)(100), so (35.45g/58.44g)(100) = 60.66% Cl. Hope this helps!

Answer:

\% Cl=61.65\%

Explanation:

Hello,

In this case, chlorine's percent composition is given by the shown below formula:

\% Cl=\frac{n_{Cl}m_{Cl}}{M_{NaCl}}*100\%

Whereas n_{Cl} accounts for the number of chlorine atoms into the NaCl, m_{Cl} for chlorine's atomic mass and M_{NaCl} for sodium chloride's molar mass, therefore, the percent composition of chlorine turns out:

\% Cl=\frac{1*35.45}{58.45}*100\%=61.65\%

Best regards.

Many enzymes are inhibited irreversibly by heavy metal ions such as Hg2+ , Cu2+ , or Ag+ , which can react with essential sulfhy
3241004551 [841]

Answer:

The minimum molecular weight of the enzyme is 29.82 g/mol

Explanation:

<u>Step 1:</u> Given data

The volume of the solution = 10 ml = 10*10^-3L

Molarity of the solution = 1.3 mg/ml

moles of AgNO3 added = 0.436 µmol = 0.436 * 10^-3 mmol

<u>Step 2:</u> Calculate the mass

Density = mass/ volume

1.3mg/mL = mass/ 10.0 mL

mass = 1.3mg/mL *10.0 mL = 13mg

<u>Step 3:</u> Calculate minimum molecular weight

Molecular weight = mass of the enzyme / number of moles

Molecular weight of the enzyme = 13mg/ 0.436 * 10^-3 mmol

Molecular weight = 29.82 g/mole

The minimum molecular weight of the enzyme is 29.82 g/mol

How many electrons would an uncharged atom of nitrogen have
dybincka [34]
The atomic number represents the number of protons in an atom's nucleus. In an uncharged atom, the number of protons is always equal to the number of electrons. For example, carbon atoms include six protons and six electrons, so carbon's atomic number is 6.
