Answer:
4 or5or6
Step-by-step explanation:
3+1=4
3+2=5
3+3=6
The pH value of a solution is a logarithmic function of the hydronium ion concentration in the solution. Since we are given the pH foe both we can easily calculate the H+ ion concentration as follows:
Aeen
3.3 = -log (H+)
H+ = 0.04 M
Marien
2.7 = - log (H+)
(H+) = 0.07 M
Therefore, Aeen's drink is 0.07/0.04 or 2 times more hydrogen ion concentration than Marien's drink.
Answer:
Explanation:
<u>1. Volume of a cup</u>
The shape of the cup is a cylinder. The volume of a cylinder is:
The diameter fo the cup is half the diameter: 2in/2 = 1in.
Substitute radius = 1 in, and height = 4 in in the formula for the volume of a cylinder:
<u>2. Volume of the sink:</u>
The volume of the sink is 1072in³ (note the units is in³ and not in).
<u>3. Divide the volume of the sink by the volume of the cup.</u>
This gives the number of cups that contain a volume equal to the volume of the sink:
