NEED HELP ASAPPP please help i will really appreciate it

3. 0.36 L to the nearest hundredth

4. 542.40 L  to the nearest hundredth

Explanation:

Question 3

Volume = 8.16 L

Number of moles = ?

At STP;

Temperature = 273 K

Pressure = 1 atm

Using the General gas equation;

PV = nRT where R = General gas constant = 0.0821

n = PV / RT

n = (1 * 8.16 ) / (0.0821 * 273)

n = 8.16 / 22.4133 = 0.3641 ≈ 0.36 to the nearest hundredth

Question 4

Volume = ?

Number of moles = 24.2 mol

At STP;

Temperature = 273 K

Pressure = 1 atm

Using the General gas equation;

PV = nRT where R = General gas constant = 0.0821

V = nRT / P

V = 24.2 * 0.0821 * 273 / 1

V = 542.402 L ≈ 542.40  to the nearest hundredth
