Science Experiments

Question: Hair/shampoo related science question…?

Okay, I’m doing a science experiment on the foaminess of shampoo.
The paper I have says:
“Pour 25 mL of your 1 percent shampoo solution into a tall, narrow diameter glass.”

So what is 1 percent shampoo solution?
And what is a diameter glass?

Thanks.
Nevermind about the glass. =p

I just need to know what 1 percent shampoo solution is.

Answer: You have to either make the solution yourself or your teacher was supposed to give it to you.

If you need to make it an easy formula would be measure out 1mL of shampoo and 99mL of water. Mix them. You now have a 100mL solution with 1mL of shampoo in it. And it is 1% shampoo solution.

Formula for percentage shampoo 1mL shampoo/100 mL solution * 100=1%

Now just measure out 25mL of it to do your experiment.
