If a lab requires each lab group to have 25ml of a solution and it takes 15 grams of CuNO3 to make 1 liter of solution how many
tino4ka555 [31]

We need to do some general algebra here.

We will find that you need 8.25 grams of CuNO₃ to make enough solution for the 22 labs.

<em>We know that:</em>

  • Each lab group needs 25 ml of solution.
  • it takes 15 g of CuNO₃ to make one L of that solution.
  • There are 22 labs.

Because each lab needs 25 ml of solution, 22 labs will need that amount 22 times, so the <u>total amount of solution needed</u> is:

22*25ml = 550 ml

Now we know that we need 15 grams to make one liter of solution, and:

1 L = 1000ml

Then you need 15g to make 1000ml

and x (we want to find this amount) to make 550ml

Then we can write two equations (not actual equations, as these are different units) like:

x = 550ml

15g = 1000ml

Now we can take the quotient between these two equations:

x/15 g = (550ml/1000ml)

And now we can solve this for x:

x = (550ml/1000ml)*15g = 8.25g

So you need 8.25 grams of CuNO₃ to make enough solution for the 22 labs.

Tatiana [17]
Darwin observed the beaks of the birds and how the different beaks helped the birds to eat different types of seeds.

This relates to natural selection because certain finches with say a smaller shorter beak would be able to eat only smaller seeds and fruits as to where a finch with a longer larger beak could eat larger bigger seeds and fruits. 

Hope this helped! Have a great day!

Explain how a nuclear power plant functions and what safety precautions must be taken to ensure the safety of the power plant, i
Talja [164]
Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Although renewable energy sources, like wind and solar power, are important resources for a country’s energy mix, only nuclear power is capable of producing large amounts of electricity 24 hours a day, 365 days a year.

For safety precaution which regards to employees, several federal agencies—the US Nuclear Regulatory Commission (NRC), the U.S. Environmental Protection Agency and the U.S. departments of Energy and Transportation—establish radiation protection regulations for U.S. nuclear plants based on internationally recognized scientific studies.

For the safety precaution of power plants itself, The NRC monitors plant performance according to three strategic areas: reactor safety, radiation safety and security.
