Question

Your mother gives you 250 mg of acetaminophen and a cup containing 500 ml of water. What is the concentration of the solution if you dissolve the Tylenol in the water?

Answer 1

The concentration is 50%

Step-by-step explanation:

Mass-Volume concentration is molarity (M) times 100% or
`(Gsolute)/(Lsoln)` * 100%

For this problem, we need to convert from milligrams to grams and milliliters to liters in order to plug the values into the equation and solve for the concentration.

So, 250 mg = 0.025g (there are 1000 mg in 1 g)

And 500ml = 0.05 L (there are 1000 ml in 1 L)

Now we can solve for the concentration

`(0.025 g)/(0.05 L)`
`* 100` %= 0.5
`* 100` % = 50% of Tylenol concentration
