Answer:
5%
Explanation:
Given parameters:
Volume of original acetone before dilution = 10ml
Volume of diluted solution = 200ml
Unknown:
Percent volume of acetone in the solution = ?
Solution:
To find the percent volume of acetone in the diluted solution, use the expression below;
Percent volume of acetone =
Insert the parameters and solve;
Percent volume of acetone = x 100 = 5%
Answer:
rA = 0.60 M/s
rC = 0.90 M/s
Explanation:
Let's consider the following reaction:
2 A+B ⇒ 3 C
The rate of each substance can be calculated like the change in its concentration divided by the change in time. Given the rate must always be positive, we add a minus sign before the reactants change in concentration.
The rate of the reaction is equal to the rate of each substance divided by its stoichiometric coefficient.
The rate of disappearance of B is 0.30 M/s.
The rate of disappearance of A is:
The rate of appearance of C is:
