After performing a western blot analysis, you obtain a blot showing a single band. Plotting electrophoretic mobility of the mark

saveliy_v [14]

Answer:

The estimate is $N = 1936$

Explanation:

From the question we are told that

The molecular weight of the protein is $MW_p = 213 kD = 213 *10^{3} \ D$

Generally the average molecular weight of amino acid is $MW_a = 110 \ D$

Generally the number of amino acids in the protein is mathematically represented as

$N = \frac{MW_p}{MW_a}$

$N = \frac}{213 *10^{3}{110}$

=> $N = 1936$

Features of carbon that makes it unique in organic chemistry

FinnZ [79.3K]

Answer:

The answer lies with carbon's unique properties. Carbon has an exceptional ability to bind with a wide variety of other elements. Carbon makes four electrons available to form covalent chemical bonds, allowing carbon atoms to form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen

Need little help pls

Julli [10]

Answer:

0.354 molal

Explanation:

The molarity (M) or the concentration of a solution is defined as the number of moles of a compound in the solution per liter of solution (mol/L), whereas molality, is defined as the number of moles of a compound in the solution per kg of the compound (mol/kg).

Given that the density of the solution is 1.202 g/mL, which is equivalent to 1.202 kg/L. Since the prefix mili- denotes a factor of one thousandth ( $10^{-3}$ ) and kilo- denotes a factor of one thousand ( ${10}^3$ ),

$1.202 \ \frac{g}{mL} \ = \ 1.202 \ \frac{g}{(10^{-3}) L} \ = \ 1.202 \ \frac{{10}^3g}{L} \ = \ 1.202 \ \frac{kg}{L}$ .

To calculate the corresponding molality of the solution, the formula

$Molality \ (mol/kg) \ = \ \frac{Molarity \ (mol/L)}{Density \ (kg/L)}$ is used.

Therefore,

$Molality \ = \ \frac{0.426 \ mol/L}{1.202 \ kg/L} \ = \ 0.354 \ mol/kg \ \ (3 \ s.f.)$

Answer:

Option 1

Explanation:

You need to make the number of each type of atom on both sides the same, and this can only be done by changing the coefficients.
