Answer:
The molarity of the solution is 4M
Explanation:
Molarity is defined as the amount of moles of solute present in one liter of solution. So the molarity of any solution can be found by dividing the moles of solute between the volume in liters of the solution.
For this case we have:

It is basically the function of evaporation.
If it is wrong i am sorry.
<h2>
Hello!</h2>
The answer is: 11,2 moles of O2
<h2>
Why?</h2>
First, we need to balance the equation in order to calculate how many moles reacts,
The balanced equation is:

So, from the equation we have that 2 moles of C2H6 reacts with 7 moles of O2, knowing that we can calculate how many moles of O2 are required to react completely with 3.2 moles of C2H6:
So, we need 11,2 moles of O2 to react completely with 3,2 moles of C2H6.
Have a nice day!
Question
<em>which cell living organism are diploid?</em>
Answer:
<em>Ploidy is the area of biology that refers to the number of chromosomes in a cell. Therefore, cells with two sets are diploid, and those with one set are haploid. In diploid organisms, such as humans, the haploid cells are used only for the sex cells for reproduction, while the rest of the cells are diploid.</em>
Hope this helps!
