Answer:
We need 5 tablets.
Explanation:
We need to prepare 250 mL of a 1 : 5 solution.
When we are talking about solutions , '' a : b '' is known as the solution ratio.
Where ''a'' and ''b'' are integer numbers.
In our exercise, we have a 1 : 5 solution ratio. This means that we will have 1 gram of solute for each 5 mL of solution.
To calculate the mass of solute we can write the following :
Notice that we equalize the solution ratio to the mass of solute '''' divided by the total volume of solution (250 mL).
Solving for ⇒
⇒
We found out that we need 50 g of solute.
Given that each tablet has 10 g of solute ⇒
We need five 10-gram tablets to prepare the solution.

Use AT as the abbreviation for athletic trainer. Use ATC only when referring to the credential. Do not use ATC/L, ATC/R, LATC or any other combination of ATC, as the credential is trademarked. NATA does not use the term “certified athletic trainers” unless the circumstance requires distinction.

The original weight is 4.
Explanation:
20%= 1/5 if u don’t know the percentage then u can simply by doing..
20/100 then u divide it. U can do this by any other numbers such as 2, 4,5,10 and 20. U can do which ever way u like but i would recommend doing it either by 10 or 20.
So if we divide it by 20 we do...
20/100 divided by 20= 1/5
Or
20/100 divided by 10= 2/10
2/10 divided by 2 = 1/5
You can see the bigger the number that fits in is faster, although u can do it any way u feel like doing.
So we have got 1/5 from 20%. Now we do...
1/5 divided by 20. So when we do this, we use the bottom number to divide it and the top number to times it.
So..
1/5 u could use as 20 divided by 5..
Then 1 times the number that u get from ur before sum.
The answer is 4.
Because 1/5= 20 divided by 5 = 4
Since we have a 1 left we do..
4 times 1 which is... 4.
( u don’t need to show these parts in doing ur working, but i am doing these so they can help u understand)
So the answer is 4 and is the original weight.
I hope this is clear and helps u! :D
