How many grams of water should be added to 4.00 g NaOH to create 2.00% by mass NaOH solution?

Answers

Answer:

196 grams

because ^^^ was wrong and person in comments said it was 196 and it was right

When NaOH of 4.00 g is being added with water, the mass of water required to create 2.00% of NaOH solution by mass is 196 g.

What is mass percent of solute?

It means that the particular amount of solute in terms of percentage is present in the solute.

Given the mass of the solute, NaOH is 4.00g

Suppose the mass of water required to add is x in g.

The mass percent of the solute is

[tex]\dfrac{2}{100} =\dfrac{4.00}{4.00 +x }[/tex]

x =196 g

Therefore, mass of water required to create 2.00% of NaOH solution by mass is 196 g.

3. Describe the process behind how students recover an individual's remains from a surface grave.

Answers

Answer:

By using the techniques of archeology.

Explanation:

Students recover an individual's remains from a surface grave by using the techniques of archeology field to scrape away the layers of soil from that remains in a way that the remains can't be damaged. If they find the remains within 10 centimeters of digging, they can dig down further in order to dig out all the remains safely. The instruments of archeology field are used because they are light and can be used to dig out fossils of ancient organisms.
