If 50 mL of pure acetone is mixed with 450 mL of water, what is the percent by volume of acetone?

Chemistry
1 answer:
slega [8]2 years ago
4 0

Answer:

10%

Explanation:

The percent by volume of acetone is given by the following formula:

% v/v = Volume of acetone / Total Volume * 100%

Now we <u>calculate the total volume of the solution</u>:

Total Volume = Volume of Acetone + Volume of Water

Total Volume = 50 mL + 450 mL = 500 mL

Then we <u>calculate the percent by volume:</u>

% v/v = 50 mL / 500 mL * 100 % = 10%

3. How many moles of silver is 8.46x1024 atoms of<br> silver?
ioda

Answer:

<h2>14.05 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{8.46 \times  {10}^{24} }{6.02 \times  {10}^{23} }  \\  = 14.053156

We have the final answer as

<h3>14.05 moles</h3>

Hope this helps you

How can Newton's Third Law of Motion be used to explain why it is difficult to walk on a slippery surface, such as ice?
Olenka [21]
E ground pushes you forward. But that interaction is friction. Reduce friction and it doesn't matter how strong your legs are, the surface is incapable of pushing you accordingly. The coefficient of static friction is very low so it is easy to slide your foot rather than push.
