Explanation:
Many abused drugs are prescription drugs.
seaweed having 50 g salt in 1 L water. The bucket contains 150 g of salt in 2 L of water
amount of water present in bucket is twice to amount of water in weed

At equilibrium, volume of water in weed is x and volume in bucket is y but concentration remain same as follows:

At equilibrium, weed loose z L from 1 L water to bucket containing 2 L as follows:

Thus, Weed will loose 0.25 L of water
Answer:
The molarity of acid is 3 M.
Explanation:
Given data:
Volume of H₃PO₄ = 25 mL
Volume of NaOH = 50 mL
Molarity of NaOH = 1.50 M
Molarity of H₃PO₄ = ?
Solution:
Formula:
M₁V₁ = M₂V₂
M₁ = M₂V₂ / V₁
M₁ = 1.50 M ×50 mL / 25 mL
M₁ = 75 M. mL / 25 mL
M₁ = 3 M
The molarity of acid is 3 M.
