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 ⇒
⇒

Given that each tablet has 10 g of solute ⇒
We need five 10-gram tablets to prepare the solution.

- Clearly rinse.
- Dry your hands using a fresh towel or let them air dry.
