Answer: The bottle has a total mass of 13000 mg of insulin.
Explanation:
We are given:
Concentration of insulin = 40 mg/mL
and we need to fins the mass of insulin in 325 mL of bottle.
From above, we know that:
1 mL contains 40 mili-grams of insulin.
So, 325 mL will contain = = 13000 mili-grams of insulin.
Hence, the bottle has a total mass of 13000 mg of insulin.
Answer: There is 125 mL of a 2.0 M CuCl2 solution are needed to make 500 mL of a 0.5 M solution
Explanation:
Given: = 2.0 M, = ?
= 0.5 M, = 500 mL
Formula used to calculate the volume is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that there is 125 mL of a 2.0 M solution are needed to make 500 mL of a 0.5 M solution.
Answer : Option A) Deforestation.
Explanation : Factors related to deforestation can lead to desertification in presence of natural drought.
As natural drought hit area is an area which has low amount of water supply in the land. It is also called as below average precipitation land when drought area is deforested it will lead to desertification. As the plants in the drought area are the reason why their is at least low water is found, if these vegetation is deforested then it will lose its capacity to hold water and the land will be deserted.
