Memorize that molarity = moles/liters and you can get these
The new lowered freezing point of the benzene mixture is determined as 2.4°C.
<h3>
Effect of impurities in freezing point</h3>
The presence of impurities lowers the vapour pressure of the solution since the concentration of the solution is increased.
Change in temperature of the new mixture = 0.613 x 5.5°C = 3.1 °C
New freezing point = 5.5°C - 3.1°C = 2.4°C
Thus, the new lowered freezing point of the benzene mixture is determined as 2.4°C.

Answer:
The more optically dense that a material is, the slower that a wave will move through the material. ... So as the index of refraction value increases, the optical density increases, and the speed of light in that material decreases.
Answer:
0.30 M
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t = ?
is the initial concentration = 1.36 M
k is the rate constant = 0.208 s⁻¹
t = 7.30 seconds
So,
Question:
<u>1.) How do plant scientists hope to improve plant processes?</u>
Answer:
<u>January 2, 2012. Plant scientists long have known they can alter crops genetically to improve performance; they've been doing it thousands of years.</u>
Question:
<u>2.) How could you find out which resources are the most important for a plant to grow?</u>
Answer:
<u>Three elements, carbon, oxygen and hydrogen, are essential to plant growth and are supplied by air and wa</u><u>ter.</u>
