Can I get help with this questions please. for a thumbs up and great rating.

Scientists have found a new kind of gas. Unfortunately, they have found that it breaks down quickly via the following reaction: 2CD3C2+3D2 Keeping a sample of CD3 in a 2.5L fixed-volume tank being kept at a temperature of 25C and an initial total pressure of 5.00 bar the scientists were able to track the production of C2, which is listed in the table below. Calculate the partial pressure of CD3 in the container when the partial pressure of C2 has reached 0.80 bar. Your
