Answer:0.102 milliliters is required
Explanation:
The easy way to obtain this is to take unit conversation very important as diphenhydramine has a molar mass of 255.355grams per mole and the concentration of the liquid diphenhydramine is 12.5 milligrams per 5 milliliters.
We have to convert the molar mass into milligrams per mole by dividing by 1000 which yields 0.255355mg/mol then;
Simplify the molar mass divided by the concentration of the liquid diphenhydramine;
0.255355/12.5/5
This equals 0.102 milliliters!
Hello!
Looking at the given ruler, we can see that the capillary tube's diameter starts at 0cm and goes to 0.4cm. That means that the diameter of this tube is 0.4 centimeters.
The problem has given us how to find the radius when we have a diameter, so we would need to divide it by 2.
0.4 cm / 2 = 0.2 cm
Therefore, the radius of the capillary tube is 0.2 centimeters.
The scientist should make a new hypothesis and do a new experiment! That is what I say!
