Answer:

Explanation:
= Concentration of stock solution
= Concentration of solution
= Volume of stock solution = 19 mL
= Volume of solution = 0.31 L= 310 mL
We have the relation


The concentration of the diluted solution will be 0.613 times the concentration of the stock solution.
Answer:The oxygen during photosynthesis comes from split water molecules. During photosynthesis, the plant absorbs water and carbon dioxide. After the absorption, the water molecules are disassembled and converted into sugar and oxygen.
When there are 14c-lable uracil that are added to the growth medium of cells, the macromolecules that will be labled are RNA. Uracil is a nucleobase that make up the DNA or the RNA. In RNA, uracil binds with other nucleobase (adenine) through hydrogen bonds.
Answer:
The answer is "
"
Explanation:
Sodium chloride solute mass
Solvent water mass
Calculating the solution mass = Solute mass + solvent mass
Calculating the percentage of concentration:
Answer:
<h2>The answer is 9 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 216 g
volume = 24 cm³
The density is

We have the final answer as
<h3>9 g/cm³</h3>
