What is the concentration (g/L) of an albumin solution made by mixing 0.20 mL of 6.0 g/L solution with 2.72 mL BCG reagent? Assume volumes are additive.

0.41g/L

Explanation:

To find the concentration of the albumin in the mixture we need to find the mass in grams and the volume in liters of the solution:

Mass of albumin:

0.20x10⁻³L * (6.0g / L) = 1.2x10⁻³g of albumin

Volume of the solution:

0.20mL + 2.72mL = 2.92mL = 2.92x10⁻³L

Thus, concentration of albumin is:

1.2x10⁻³g of albumin / 2.92x10⁻³L =

b is the correct

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
