Name: 2. The planet Venus is an inhospitable place, with a surface temperature of 560°C and a surface pressure of 90.0 atm. The mole fractions of the main gases in the atmosphere are 0.96 for CO2 and 0.030 for N2, with trace amounts of other gases, including water, sulfur dioxide, and sulfuric acid. Calculate the partial pressures of CO2 and N2 in Venus' atmosphere. (4 points)

00:01 Hello everyone, in this question the given information is 96 % of carbon dioxide and 3 % of nitrogen.

00:10 So as by this one, we came to conclude that 100 grams of air contains 96 grams of carbon dioxide and 3 grams of nitrogen.

00:21 That is the information is conveyed from this one.

00:23 Okay, so now let us calculate the number of modes of carbon dioxide.

00:28 Number of moles can be calculated as the given weight by molecular weight.

00:33 Here the given weight is 96 grams and a molecular weight of carbon dioxide is 44.

00:38 If you saw this one, we will get it as 2 .181818.

00:43 This is a number of moles of carbon dioxide.

00:45 Similarly, let us calculate the number of moles of nitrogen.

00:49 It can be calculated as given weight is 3 grams, 3 divided by the molecular weight of nitrogen is 28.

00:56 3 divided by 28.

00:58 We will get a 0 .1071 mode.

01:00 This is the number of molds of nitrogen.

01:03 Okay.

01:04 Now let us calculate the mold fraction.

01:07 So here mold fraction can be calculated as a mold fraction of carbon dioxide.

01:15 It is nothing but number of carbon dioxide divided by total number of modes of carbon dioxide.

01:20 We know that 1 .2 .1818.

01:23 So total number of modes is nothing but number of modes of carbon dioxide number of that is nothing but 2 .1818 plus 0 .171.

01:35 Okay, if we saw this one, we'll use the 0 .9532...
