A. The new molarity of the diluted solution is 0.047 M

B. The new molarity of the diluted solution is 0.188 M

C. The new molarity of the diluted solution is 4.4 M

D. The new molarity of the diluted solution is 1.28 M

A. How to determine the new molarity

  • Volume of stock solution (V₁) = 26.6 mL
  • Molarity of stock solution (M₁) = 0.127 M
  • Volume of water = 45.4 mL
  • Volume of diluted solution (V₂) = 26.6 + 45.4 = 72 mL
  • Molarity of diluted solution (M₂) =?

M₁V₁ = M₂V₂

0.127 × 26.6 = M₂ × 72

Divide both side by 72

M₂ = (0.127 × 26.6) / 72

M₂ = 0.047 M

B. How to determine the new molarity

  • Volume of stock solution (V₁) = 49.5 mL
  • Molarity of stock solution (M₁) = 0.757 M
  • Volume of water = 150 mL
  • Volume of diluted solution (V₂) = 49.5 + 150 = 199.5 mL
  • Molarity of diluted solution (M₂) =?

M₁V₁ = M₂V₂

0.757 ×49.5 = M₂ × 199.5

Divide both side by 199.5

M₂ = (0.757 × 49.5) / 199.5

M₂ = 0.188 M

C. How to determine the new molarity

  • Volume of stock solution (V₁) = 102 mL
  • Molarity of stock solution (M₁) = 25.8 M
  • Volume of water = 500 mL
  • Volume of diluted solution (V₂) = 102 + 500 = 602 mL
  • Molarity of diluted solution (M₂) =?

M₁V₁ = M₂V₂

25.8 × 102 = M₂ × 602

Divide both side by 602

M₂ = (25.8 × 102) / 602

M₂ = 4.4 M

D. How to determine the new molarity

  • Volume of stock solution (V₁) = 741 mL
  • Molarity of stock solution (M₁) = 1.81 M
  • Volume of water = 308 mL
  • Volume of diluted solution (V₂) = 741 + 308 = 1049 mL
  • Molarity of diluted solution (M₂) =?

M₁V₁ = M₂V₂

1.81 × 741 = M₂ × 1049

Divide both side by 1049

M₂ = (1.81 × 741) / 1049

M₂ = 1.28 M

In which of the following substances do you find strong hydrogen bonding?
makvit [3.9K]

Answer:

The strength of an individual H bond depends on the polarity of the H-X bond and therefore on the electronegativity of X ( the more delta positive the H atom, the stronger the electrostatic force of attraction between it and a lone pair of electrons). Thus, on a per bond basis, HF H bonding is strongest. However, as water has two H atoms, each molecule can form two H bonds so on a per molecule basis, water H bonding is strongest (this is evidenced by the boiling points of the three substances; NH3 < HF < H2O.)

A 32 year old immigrant from a patriarchal country is giving birth. As she is delivering the baby, she tearfully confesses to he
Wittaler [7]

She's 32. She can vote. She is entitled to privacy and it would take almost an act of Nature to disclose what she has asked of her doctor.

HIPAA has to do with who can look at medical records. If she doesn't want her husband to see those records, they are locked tighter than a safe on Wall Street.

From what I've read, that ruling has many implications. He is her next of kin. Can he sue if something goes wrong? There are more questions here than answers. Will the records be opened if something does go wrong? Where does freedom from prying eyes end and the good of the commonwealth begin?

If this question is anything but a school question (I'm assuming that is all it is), and somebody needs to act on the answer, for goodness sake consult someone who really knows and is governed by HIPAA. This is nothing to fool around with.
