Question

Find the number of molecular in 22.4 * 10^3 mL of CO2 gas at STP

Answer 1

Answer:

6×10^23 molecules

Explanation:

since since 22400 ml has avogadro number of molecules (fact) then 22400 ml will be having avogadro the number of molecules

Answer 2

The number of molecules of CO₂ gas is 6.023 × 10²³.

Given:

The volume of CO₂ gas at STP is 22.4 × 10³ mL

To Find:

The number of molecules in the volume of CO₂ gas at STP is 22.4 * 10³ mL.

Solution:

We are required to find the number of molecules in the volume of CO₂ gas at STP is 22.4 × 10³ mL.

The number of molecules of the gas is given as

Number of molecules = number of moles(n)×Avogadro's number ------(1)

Number of moles = Given volume / Volume of gas at STP -----(2)

Given volume = 22.4 × 10³ mL

The volume of gas at STP =  22.4 × 10³ mL

Number of moles = 22.4 × 10³ mL/22.4 × 10³ mL

number of moles(n) = 1

avogadro's number = 6.023 × 10²³

On substituting the values of the number of moles(n) and Avogadro's number in equation(1) we get

Number of molecules = 1×6.023 × 10²³

Therefore, The number of molecules of CO₂ gas is 6.023 × 10²³.
