There are many factors that influence the population changes of an ecosystem. Which of these does not influence population size
devlian [24]

Answer:

B. An animal's weight

Explanation:

An animal's weight is the factor that does not influence population size in an ecosystem because this factor does not cause an increase or decrease the population of animals in an ecosystem. The birth and death rate of animals and number of animals in habitats are the factors that tells us about the increase and decrease in the population of organisms in an ecosystem but weight of organism can't affect the population.

To prepare 1.00 L of 14g BaCl2, what Molarity would it be?​
nikklg [1K]

Answer:

0.067 M  

Explanation:

Given data:

Volume of solution = 1.00 L

Mass of BaCl₂ = 14 g

Molarity of solution = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Now we will calculate the number of moles first.

Number of moles = mass/ molar mass

Number of moles = 14 g/ 208.23 g/mol

Number of moles = 0.067 mol

Now we will calculate the molarity.

Molarity = 0.067 mol / 1.00 L

Molarity  = 0.067 M    ( mol/L=M)
