In a mixture of gases, the volume content of a gas is 0.06% at STP. Calculate the number of molecules of the gas in 1 L of the mixture.

Options

A. `1.613xx10^23`
B. `6.023xx10^23`
C. `1.61xx10^27`
D. `1.61xx10^19`

Explanation

To solve the problem of calculating the number of molecules of a gas in a mixture where the volume content of the gas is 0.06% at STP, we can follow these steps:

### Step 1: Calculate the volume of the gas in 1 liter of the mixture
Given that the volume content of the gas is 0.06%, we can calculate the volume of the gas in 1 liter of the mixture.

\[ \text{Volume of gas} = \frac{0.06}{100} \times 1 \, \text{L} = 0.0006 \, \text{L} = 6 \times 10^{-4} \, \text{L} \]
