What is the molarity of the bleach solution of slide 28 (7.4% NaOCl by mass, density 1.12 g.cm-3)?
Anuta_ua [19.1K]

Answer:

Molarity of solution is 1.10x10⁻³ M

Explanation:

Solute NaOCl

7.4% by mass means, that in 100 grams of solution, we have 7.4 g of solute.

Molar mass of NaOCl = 74.45 g/m

Mol = Mass / Molar mass

7.4 g / 74.45 g/m = 0.099 moles

Density of solution = 1.12 g/mL

Density = Mass / volume

1.12g/mL = 100 g / volume

Volume = 100 g / 1.12g/mL = 89.3 mL

Molarity = mol /L

89.3 mL = 0.0893 L

0.099 moles / 0.0893 L = 1.10x10⁻³ M

A hypothetical covalent molecule, X–Y, has a dipole moment of 1.93 1.93 D and a bond length of 109 pm. 109 pm. Calculate the par
Gnesinka [82]

Answer:

q= 110.5 ke

Explanation:

Dipole moment is the product of the separation of the ends of a dipole and the magnitude of the charges.

μ = q * d

μ= Dipole moment (1.93 D)

q= partial charge on each pole

d= separation between the poles(109 pm).

e= electronic charge ( 1.60217662 × 10⁻¹⁹ coulombs)

So,

q= \frac{1.93}{109 * 10^{-12} } coulombs

q = \frac{1.93}{109 * 10^{-12} *  1.60217662 * 10^{-19} } e

q = 1.105 * 10⁵ e

q= 110.5 ke
