The volume of the box is 8.6 × 10³ in².
<em>V = lwh</em> = 26 in × 18.4 in × 17.92 in = 8.6 × 10³ in²
<em>Note</em>: The answer can have only <em>two significant figures</em> because that is all you gave for the length of the box.
Answer:
a. very acidic
Explanation:
A solution with a pH of 1.6 would be described as a very acidic solution.
The pH scale is a convenient scale for expressing the level of acidity or alkalinity of aqueous solutions.
The scale ranges from 1 to 14 in which case 1 is the lower limit and 14 the upper limit.
- An acidic solution has a pH value less than 7. As pH decreases, the acidity of the solution increases.
- Neutral solutions have a pH of 7
- An alkaline solution has a pH greater than 7 and the level of alkalinity increases as pH increases.
Answer:
4
Explanation:
Mass divided by Volume = Density
The objects mass is 200 grams and the volume of the water displaced is 50
So 200 divided by 50 equals 4
Answer:
It reads as follows: 0.5 moles of solute per liter of solution.
Explanation:
Molarity is the most frequent way of expressing the concentration of solutions in chemistry, and it indicates the number of moles of solute dissolved per liter of solution; is represented by the letter M.
38 g / (3 x 10^23 molecules) * 6,02x10^23 molecules/mol = 76,25 g/mol.
