I tried this question but just cant get it. atmospheric pressure on the surface of Mars is about 6.0mmHg the partial pressure of carbon dioxide is 5.7mmHg. what percent of the Martian atmosphere is CO2?
%CO2 = (pCO2/Ptotal) x 100 = ?
To calculate the percentage of carbon dioxide (CO2) in the Martian atmosphere, we can use the concept of partial pressure. Partial pressure is the pressure exerted by each individual gas in a mixture, assuming all other gases are removed.
To find the percentage of CO2, we need to determine its partial pressure as a fraction of the total atmospheric pressure. We can use the formula:
Percentage of CO2 = (Partial pressure of CO2 / Total atmospheric pressure) * 100
Given that the atmospheric pressure on the surface of Mars is about 6.0 mmHg and the partial pressure of CO2 is 5.7 mmHg, we can substitute these values into the formula:
Percentage of CO2 = (5.7 mmHg / 6.0 mmHg) * 100
Simplifying this expression:
Percentage of CO2 = 0.95 * 100
Therefore, the percentage of carbon dioxide in the Martian atmosphere is approximately 95%.
To calculate this, you can divide the partial pressure of CO2 by the total atmospheric pressure and then multiply the result by 100.
