The correct option is (C) 6.02 X 10²³

A sample of CH₄O with a mass of 32.0 g contains <u>6.02 X 10²³</u> molecules of CH₄O.

To calculate the number of moles;

Molar mass of CH₄O = C + 4(H) + O

          = 12.01 + 4(1.008) + 16

          = 32.04 g/mol

So, 1 mol of CH₄O = 32.04 g of CH₄O

Given, 32.0 g of CH₄O

According to Avagadro's constant 1 mole of a substance contains 6.022× 10^23 particles (molecules, atoms or ions).

 = (32.0 g/1)(1 mol CH₄O/32.04 g CH₄O)(6.02x10²³/1 mol CH₄O)

 = 6.02 X 10²³ molecules of CH₄O

Hence, a sample of  will contain  number of molecules 6.02 X 10²³ molecules.

A sample of oxygen gas has a volume of 36.7 L at 145 kPa and 65. ̊C. What volume will the sample have at STP?
xxTIMURxx [149]
Data Given:

                  Initial Volume = V₁ =  36.7 L

                  Initial Pressure = P₁ =  145 kPa

                  Initial Temperature = T₁ =  65 °C + 273 = 338 K

                  Final Volume = V₂ = ?

                  Final Pressure = P₂ = 101.325 kPa           (Standard Pressure)

                  Final Temperature = T₂ = 273 K                (Standard Temperature)

Formula used:
                      As number of moles are constant, so Ideal Gas equation in following form is used,
                                        P₁ V₁ / T₁  =  P₂ V₂ / T₂
Solving for V₂,
                                    V₂  = P₁ V₁ T₂ / T₁ P₂
Putting Values,

                  V₂ = (145 kPa × 36.7 L × 338 K) ÷ (273 K × 101.325 kPa)

                  V₂ = 1798667 ÷ 27661.25

                  V₂ = 65.02 L

How are real Gases Different from ideal Gases?
madam [21]

Answer:

Explanation

Explanation:

Real gases have small attractive and repulsive forces between particles and ideal gases do not. Real gas particles have a volume and ideal gas particles do not. Real gas particles collide in-elastically (loses energy with collisions) and ideal gas particles collide elastically.
