B.) As land plants became more complex, animal life did as well.
<u>The plants have also adapted to reduce the water loss across cell walls. This is made possible by waxy cuticles.</u>
Answer:
1.750 M
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid ,
M₂ = concentration of base,
V₂ = volume of base .
from , the question ,
M₁ = ? M
V₁ = 7.14 mL
M₂ = 0.250 M
V₂ = 50 mL
Using the above formula , the molarity of acid , can be calculated as ,
M₁V₁ = M₂V₂
M₁ * 7.14 mL = 0.250 M * 50mL
M₁ = 1.750 M
Hence, the molarity of the hydrochloric acid = 1.750 M
Answer: a) No, both are different.
b) Ramesh- 9.9%
Sarika - 10%
Explanation:
According to the solution prepared by Ramesh,
Mass of sugar he took (Solute) = 10 g
Mass of water he took (Solvent) = 100 g
Thus Mass % of the solution =
According to the solution prepared by Sarika,
Mass of sugar she took (Solute) = 10 g
Mass of Solution she took = 100 g
Thus Mass % of the solution =
