What volume of 0.200 M ethanol solution contains each of the following amounts?

Papessa [141]

Answer:

A. 2.3 L

B. 6.10 L

C. 0.060 L

Explanation:

The question asks the volume of a 0.200 M solution of ethanol that contains certain number of moles of ethanol.

The M in the 0.200 M stands for Molarity. This is a unit of concentration that can be expressed as:

Molarity = moles of solute / Liters of solution

In this case:

0.200 M = moles of ethanol / Liters of solution

So from the formula we can get that we can calculate the volume of the solution, as Liters of solution, given the moles in each case as:

Liters of solution = moles of ethanol / 0.200 moles/L

_______________________________________________

A. 0.45 mol ethanol

Liters of solution = 0.45 moles / 0.200 moles/L = 2.25 L = 2.3 L

B. 1.22 mol ethanol

Liters of solution = 1.22 moles / 0.200 moles/L = 6.10 L

C. 1.2 x 10⁻² mol ethanol

Liters of solution = 1.2 x 10⁻² moles / 0.200 moles/L = 0.060 L

_______________________________________________

Note: Each answer is given with the correct number of significant figures which results from the least number of significant figures in the given used values in each calculation.

Do you think it is possible to be an environmentalist without also being an environmental activist? Why or why not?

Ne4ueva [31]

Answer: Yes.

Explaination: While some environmentalists choose to actively support each other (in other words, be environmental activists) a lot of environmentalist help keep the environment healthy without continuously or actively supporting the cause. For example, some people quietly take care of the environment while keeping to themselves, while others spread awareness, fund organizations, and help keep the environment clean by making an impact.
