Question

How many Liters are in 13 moles Acetylene (C2H2) at STP?

Answer 1

To find the number of Liters in 13 moles of Acetylene (C2H2) at STP, we use the Ideal Gas Law equation. Plugging in the given values, we find that there are approximately 302.19 Liters.

Step-by-step explanation:

To determine the number of liters in 13 moles of acetylene (C2H2) at STP, we need to use the Ideal Gas Law. The Ideal Gas Law equation is PV = nRT, where P is pressure, V is volume, n is moles, R is the ideal gas constant, and T is temperature. At STP (standard temperature and pressure), the pressure is 1 atm and the temperature is 273.15 K. Since we are given the number of moles (13) and want to find the volume, we rearrange the equation to solve for V: V = nRT/P.

Plugging in the values, we get V = (13 mol)(0.08206 L·atm/mol·K)(273.15 K)/(1 atm) = 302.19 L.

Answer 2

291.2L

Step-by-step explanation:

Given parameters:

Number of moles of acetylene = 13moles

Unknown:

Volume of acetylene at STP = ?

Solution:

The problem can be solved by applying the equation that shows the relationship between the volume of gases at STP and their number of moles.

Volume of gas at STP = number of moles x 22.4

Input the variables and solve;

Volume of gas at STP = 13 x 22.4 = 291.2L
