Answer:
False
Explanation:
A community consists of all the organisms in an ecosystem that belong to the same species. Population density occurs when two or more organisms seek the same resource at the same time. A carrying capacity is anything that restricts the number of individuals in a population.
First convert the 590.0 grams of water to liters of water.
590.0 grams x (1 L / 1000 grams) = 0.59 L
Since we're dealing with concentration, recall this formula:
Molarity (M) = (moles of solute) / (liters of solution)
We know the Molarity and the Liters
0.82 M = (moles) / 0.59 L
To find the moles multiply 0.59 on both sides.
The result is 0.4838 moles of CaCl (the solute).
Then change moles into grams because the question wants grams.
In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass which is 110.986.
(0.4838 moles CaCl2) x (110.986 g CaCl)/ 1 mol CaCl2
<h2><u>
= 53.7g CaCl</u></h2>

Answer:
0.51M
Explanation:
Given parameters:
Initial volume of NaBr = 340mL
Initial molarity = 1.5M
Final volume = 1000mL
Unknown:
Final molarity = ?
Solution;
This is a dilution problem whereas the concentration of a compound changes from one to another.
In this kind of problem, we must establish that the number of moles still remains the same.
number of moles initially before diluting = number of moles after dilution
Number of moles = Molarity x volume
Let us find the number of moles;
Number of moles = initial volume x initial molarity
Convert mL to dm³;
1000mL = 1dm³
340mL gives = 0.34dm³
Number of moles = initial volume x initial molarity = 0.34 x 1.5 = 0.51moles
Now to find the new molarity/concentration;
Final molarity = = = 0.51M
We can see a massive drop in molarity this is due to dilution of the initial concentration.
