CHEM HELP PLSSSSS, I SUCK AT CHEM

Chemistry

Answer:

The answer to your question is because of surface tension

Explanation:

Surface tension is defined as the property of the surface of a liquid that allows  it to resists an external force.

From the definition, we conclude that the molecules at the surface of water are extremely close and do not allow certain bugs to penetrate it so they can walk through it.

While the molecules at the surface of octane are not as close as those molecules in water so a bug sinks on it.

In conclusion, the surface tension of water is higher than the surface tension in octane.

Calculate the number of moles of solute present and the number of grams
nekit [7.7K]

Answer:

The answer is: 18 moles and 1341, 72 grams of KCl

Explanation:

The molarity is defined as the moles of solute ( in this case KCl) in 1 liter of solution:

1L solution-----3 moles of KCl

6L solution-----x= (6L solutionx 3 moles of KCl)/1 L solution= <em>18 moles of KCl</em>

<em></em>

We calculate the weight of 1 mol of KCl:

Weight 1 mol KCl= Weight K + Weight Cl= 39,09 g + 35, 45 g=74, 54 g/mol

1 mol KCl----- 74, 54 g

18 mol KCl----x= (18 mol KCl x 74, 54 g)/1 mol KCl=<em>1341, 72 g</em>
