A high blood alcohol concentration is considered to be 0.25 g/dL. What is the molarity of this blood alcohol (CH3CH2OH) level?

0.054 M

Explanation:

A high blood alcohol concentration is considered to be 0.25 g/dL. We will express it in g/L, considering that 1 L = 10 dL.

0.25 g/dL × (10 dL/1 L) = 2.5 g/L

The molar mass of this blood alcohol (ethanol) is 46.07 g/mol. The molarity of this alcohol (moles of solute per liter of solution) is:

2.5 g/L × (1 mol/46.07 g) = 0.054 mol/L = 0.054 M

answer; natural resources;

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
