Answer:
0.628 M.
Explanation:
In order to solve this problem we need to keep in mind the<em> definition of molarity</em>:
- Molarity = moles / liters
We are given both the <em>number of moles and the volume of solution</em>, meaning we can now proceed to <u>calculate the molarity</u>:
- Molarity = 0.220 mol / 0.350 L
Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow called hemocytoblasts give rise to all of the formed elements in blood. If a hemocytoblast commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.
Based on the table and the equation of reaction; the
- rate of consumption of oxygen between time 20 and 40s is 0.005 M/s
- rate of consumption of oxygen between time 40 and 60s is 0.0025 M/s
<h3>What is rate of a reaction?</h3>
The rate of a reaction is the rate at which reactants molecules are consumed or products are formed.
- Rate of reaction = change in concentration of reactants or products/ time taken
Based on the equation of reaction, the rate of consumption of oxygen is equal to the rate of consumption of methane.
Thus. rate of consumption of oxygen from time 20 seconds to time 60 seconds is calculated as follows:
Rate between 20 and 40 = 1.0 - 0.9/20
- Rate of consumption of oxygen = 0.005 M/s
Rate between 40 and 60 = 0.9 - 0.85/20
- Rate of consumption of oxygen = 0.0025 M/s
Therefore, the rate of consumption of oxygen decreases with time.
