Answer: The molarity of each of the given solutions is:
(a) 1.38 M
(b) 0.94 M
(c) 1.182 M
Explanation:
Molarity is the number of moles of a substance present in liter of a solution.
And, moles is the mass of a substance divided by its molar mass.
(a) Moles of ethanol (molar mass = 46 g/mol) is as follows.
Now, molarity of ethanol solution is as follows.
(b) Moles of sucrose (molar mass = 342.3 g/mol) is as follows.
Now, molarity of sucrose solution is as follows.
(c) Moles of sodium chloride (molar mass = 58.44 g/mol) are as follows.
Now, molarity of sodium chloride solution is as follows.
Thus, we can conclude that the molarity of each of the given solutions is:
(a) 1.38 M
(b) 0.94 M
(c) 1.182 M
Answer:
a. 0.0022 M/s
b. 0.0011 M/s
Explanation:
Let's consider the following reaction.
2 NO(g) + O₂(g) → 2 NO₂(g)
The rate of disappearance of NO is 0.0022 mol NO. L⁻¹.s⁻¹
<em>a. At what rate is NO₂ being formed?</em>
The molar ratio of NO to NO₂ is 2:2. The rate of formation of NO₂ is:
<em>b. At what rate is molecular oxygen reacting?</em>
The molar ratio of NO to O₂ is 2:1. The rate of disappearance of O₂ is:
