There are 1.66 \times 10^{22} molecules in 1 gram of nicotine.

<u>Explanation</u>:

Nicotine is an organic compound with the chemical formula of C_{10} H_{14} N_{2}

Given  the mass of nicotine = 4.50 g

Molecular mass of Nicotine = 162.23 g/mol

Moles of a compound = given mass / molar mass of the compound

                                     = \frac{4.50}{162.23}  = 0.0277

The Number of molecules of compound:

Moles \times Avogadro number = 0.0277 \times 6.023 \times 10^{23}

                                             = 1.66 \times 10^{22} molecules.

There are 1.66 \times 10^{22} molecules in 1 gram of nicotine.

A binding protein binds to a ligand l with a kd of 400 nm what is the concentration of ligand when y is 0.25
vampirchik [111]

Answer:

The answer is 7600 nm.

Explanation:

As, Y = 0.25 = [ L ÷ (400 + (L)]

0.95 x 400 + 0.25 [ L] = [ L ]

380.25  = [ L ] - 0.95 [ L ]

              = 0.05 [L]

[L] = 380 ÷ 0.05 = 7600nm
