2. 3. For her chemistry experiment, Marisol needs 2 liters of a 50% alcohol solution. The lab has two containers, one with 40% a

lcohol solution and the other with 80% alcohol solution a.) Write a system of linear equations that you can use to determine how many liters of each type of alcohol solution Marisol should combine to get 2 liters of a 50% alcohol solution. Be sure to define your variables.
b.) Solve the system and determine how many liters of each type of alcohol solution Marisol should combine. Show all your work. *Really need help with this I have no clue what to do?

Semimetals is a term which refers to

I guess you could call them that. In chemistry, we call them Metalloids though.

Air trapped in a cylinder fitted with a piston occupies 145 mL at 1.08 atm
pav-90 [236]

Answer: 0.0014 atm

Explanation:

Given that,

Original pressure of air (P1) = 1.08 atm

Original volume of air (T1) = 145mL

[Convert 145mL to liters

If 1000mL = 1l

145mL = 145/1000 = 0.145L]

New volume of air (V2) = 111L

New pressure of air (P2) = ?

Since pressure and volume are given while temperature is held constant, apply the formula for Boyle's law

P1V1 = P2V2

1.08 atm x 0.145L = P2 x 111L

0.1566 atm•L = 111L•P2

Divide both sides by 111L

0.1566 atm•L/111L = 111L•P2/111L

0.0014 atm = P2

Thus, the new pressure of air when the volume is decreased to 111 L is 0.0014 atm
