n (NaOH) = 0.05 moles
Mass= Mr(NaOH) × moles
Mass= (23+16+1) × 0.05
Mass=2.15 g (2.15 grams)

Answer:
1. b
2. a
Explanation:
1. The density of an object represents the mass per unit volume of the object. A density of 0.45 g/mL means that 1 mL of the object weighs 0.45 g, 1.000 g/mL means 1 mL weighs 1 g, etc.
<u>A density of 35,885 g/mL means that 1 mL of the object weighs 35,885 g. This is a ridiculously high amount of weight for an object with a volume of 1 mL and seems not reasonable. It is highly unlikely that such a substance exists in nature.</u>
2. <u>Considering the fact that only rock would sink in water of all the substances from a - d, it thus means that rock would have the greatest density.</u> Oil, oxygen, and ice will all float on water, meaning that they are less dense than water.
Explanation:
As the given reaction equation is as follows.
Hence, expression for of this reaction is as follows.
Now, putting the given values into the above expression as follows.
=
=
Thus, we can conclude that the value of is .
Answer:
Explanation:
The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells.
