Answer:

600k

Explanation:

In this problem, we need to use a gas law that relates temperature to volume. The gas law to use here is the Charles’ law.

The Charles’ law posits that temperature and volume are directly proportional, provided that the pressure is kept constant.

Mathematically:

V1/T1 = V2/T2

We are looking at getting V2, hence we can write the mathematical equation as:

T2 = V2T1/V1

Asides the fact that we know that the gas is monoatomic, we do not know its volume. Let its initial volume be v. Since it expanded adiabatically, this means that its new volume is 2v

Hence: V1 = v , V2 = 2v , T1 = 300k and T2 is ?

Substituting these values, we have the following:

T2 = (2v * 300)/v

T2 = 600k

The mass of a large order of french fries is about 170 G what is its approximate weight in pounds
kap26 [50]

Answer:

             0.374 Pound Approximately

Solution:

Gram and Pound are related as,

1 Gram  =  0.0022 Pound (approximately)

As we are given with 170 g of French Fries, so it can be converted into pounds as,

          1 Gram  =  0.0022 Pound

So,

          170 Grams  =  X Pounds

Solving for X,

                      X =  (170 Gram × 0.0022 Pounds) ÷ 1 Gram

                      X =  0.374 Pound Approximately

20. What volume of 0.350M KMnO4 solution must be diluted to prepare 600. mL of
Dafna1 [17]

Answer:

25.7 mL

Explanation:

Step 1: Given data

  • Initial volume (V₁): ?
  • Initial concentration (C₁): 0.350 M
  • Final volume (V₂): 600 mL
  • Final concentration (C₂): 0.150 M

Step 2: Calculate the volume of the initial solution

We have a concentrated solution and we want to prepare a diluted one. We can calculate the initial volume using the dilution rule.

C₁ × V₁ = C₂ × V₂

V₁ = C₂ × V₂ / C₁

V₁ = 0.150 M × 600 mL / 0.350 M

V₁ = 25.7 mL
