What is the percent-by-mass concentration of acetic acid (CH3COOH) in a vinegar solution that contains 51.80 g acetic acid in a
Semenov [28]

Answer : The percent-by-mass concentration of acetic acid is, 5.15 %

Explanation : Given,

Mass of acetic acid = 51.80 g

Density of solution = 1.005 g/ml

Volume of solution = 1.000 L = 1000 ml      (1 L = 1000 ml)

First we have to calculate the mass of solution.

\text{Mass of solution}=\text{Density of solution}\times \text{Volume of solution}

\text{Mass of solution}=1.005g/ml\times 1000ml=1005g

Now we have to calculate the percent-by-mass concentration of acetic acid.

\% \text{ by mass of acetic acid}=\frac{\text{Mass of acetic acid}}{\text{Mass of solution}}\times 100

Now put all the given values in this formula, we get:

\% \text{ by mass of acetic acid}=\frac{51.80g}{1005g}\times 100=5.15\%

Therefore, the percent-by-mass concentration of acetic acid is, 5.15 %

Zolol [24]

Answer:

I believe the answer is Newton's Second Law

Explanation:

Newton's Second Law states that the acceleration of an object will count on how much mass and the amount of force that is applied.

The bowling ball was dropped from the 10th story window and had more force than when the ball was dropped from the 5th story window because the 10th story window gave the bowling ball more acceleration.
