Explanation / Answer

I am solving the first four problem as per Chegg guidelines, post multiple question to get the remaining answers

Q1)

Using ideal gas equation

PV = nRT

Since the number of moles and Temperature are kept constant, so we can use

P1V1 = P2V2

1.2 * 25 = 5.5 * V2

V2 = 5.45 mL

In significant figures, the final answer must be Option A (5.5 mL)

2)

Using ideal gas equation

PV = nRT

V1/n1 = V2/n2

V2 = (n2/n1) * V1 = (0.66/0.29) * 3.8 = 8.6 L

Correct answer is Option C

3)

Using ideal gas equation

V1/T1 = V2/T2

2/(273+25) = 6/T2

T2 = 3 * 298 = 894K

Hence the correct answer is Option E

4)

The correct answer is Option D (Charles Law)
