1. The molarity of the stock solution is 1.26 M
2. The molarity of the diluted solution is 0.126 M
<h3>1. How to determine the molarity of stock solution </h3>
From the question given above, the following data were obtained
- Mole of KIO₃ = 6.05 mole
- Volume = 4.8 L
- Molarity of stock solution =?
Molarity = mole / Volume
Molarity of stock solution = 6.05 / 4.8
Molarity of stock solution = 1.26 M
<h3>2. How to determine the molarity of the diluted solution </h3>
- Molarity of stock solution (M₁) = 1.26 M
- Volume of stock solution (V₁) = 10 mL
- Volume of diluted solution (V₂) = 100 mL
- Molarity of diluted solution (M₂) =?
M₁V₁ = M₂V₂
1.26 × 10 = M₂ × 100
12.6 = M₂ × 100
Divide both side by 100
M₂ = 12.6 / 100
M₂ = 0.126 M
Complete question
An aqueous potassium iodate stock solution is made by dissolving 6.05 mol KIO3 in sufficient water for the final volume of the solution to be 4.80 L.
Calculate the molarity of the stock KIO3 solution.
A 10.0 mL aliquot is removed from the described stock solution and diluted to a total volume of 100.0 mL.
Calculate the molarity of the dilute solution

The gastrocnemius is more effective as a plantar flexor when the knee is: fully extended
<h3>What happens with a force at a knee joint muscle?</h3>
The gastrocnemius with the soleus, is the main plantar flexor of the ankle joint. The muscle is also a powerful knee flexor. It is not able to exert full power at both joints simultaneously, for example when the knee is flexed, gastrocnemius is unable to generate as much force at the ankle.
As the front leg in gait is moving through towards swing phase, the tibia is slowed down by eccentric lengthening of the gastrocnemius and a number of other calf muscles. This slowing along with the momentum of the body creates knee extension as it pulls back on the distal femur as ankle dorsiflexion is decelerated

A person who is physiologically dependent on a drug will experience freedom from the constant use of the drug upon cessation of use.
<h3>What is physiological dependent?</h3>
Physiological dependent occurs when an individual cannot do without the use of certain drugs.
The use of the drug can affect health, relational attitude and social duties. It often results into abuse of drugs and withdrawal from the use leads to freedom of the individual.
Therefore, A person who is physiologically dependent on a drug will experience freedom from the constant use of the drug upon cessation of use.
