Question

Calculate the volume of each gas sample at STP. A. 22.8 mol Cl2. Express your answer using three significant figures. B. 4.6 mol nitrogen. C. 2.4 mol helium. D.22 mol CH4.

Answer 1

A) 1 mole of Cl2 = 22.4 L

22.8 mol of Cl2 =

= 22.8 mol of Cl2 *( 22.4 L / 1 mole of Cl2)

= 511 L

Therefore, the volume of 22.8 mol of Cl2 = 511 L

B) 1 mole of N2 = 22.4 L

4.6 mol of N2 =

= 4.6 mol of N2 *( 22.4 L / 1 mole of N2)

= 103 L

Therefore, the volume of 4.6 mol of N2 = 103 L

C) 1 mole of He = 22.4 L

2.4 mol of He =

= 2.4 mol of He *( 22.4 L / 1 mole of He)

= 53.8 L

Therefore, the volume of 2.4 mol of He = 53.8 L

D) 1 mole of CH4 = 22.4 L

22 mol of CH4 =

= 22 mol of CH4 *( 22.4 L / 1 mole of CH4)

= 493 L

Therefore, the volume of 22 mol of CH4 = 493 L
