Found this on the web! "The particles of gases are negligibly small compared to the distance between them, ... This is because an increase in the number of particles in the same volume will increase the number of collisions to the walls of the container, which causes pressure to increase."

hope this helps

much love. :)

Explanation:

According to ideal gas equation, PV = nRT.

When more is the concentration of particles of a gas it means more number of molecules or more number of moles are present.

As pressure is directly proportional to number of moles of a gas. Therefore, when there are more number of moles of a gas then there will be more number of collisions.

As a result, there will be increase in pressure.

Thus, we can conclude that the game pressure of a gas is directly related to its concentration of particles.

Using Dimensional Analysis

Explanation:

Step 1: Define

6.7 × 10²⁴ molecules NO₂ (Nitrogen dioxide)

Step 2: Define conversions

Avogadro's Number

Molar Mass of N - 14.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of NO₂ - 14.01 + 2(16.00) = 46.01 g/mol

Step 3: Use Dimensional Analysis

$6.7 \cdot 10^{24} \ molecules \ NO_2(\frac{1 \ mol \ NO_2}{6.022 \cdot 10^{23} \ molecules \ NO_2} )(\frac{46.01 \ g \ NO_2}{1 \ mol \ NO_2} )$ = 511.901 g NO₂
