So four propane. We can mostly gusset for public radio hour or can stove. And if we have 85.5, Grandma Propane on the pope informed I C three h eight. What would be the lumber? More for Pete. So first of all, again, we had to find a, um um or the massive propane. So we have three Harvin's. So we're three times Well, plus, we're, um, hydrogen. So we should be with the finances of our fine four grand for moles. Okay, so the number more propane will be close to our to our total mass team Graham developed by them with a massive for four grand for Turnbow. So, uh, we have 85.5. You went by 44 So we have 1.94 Most off. Okay. All right, second part, maybe we have to find a massive captain in the 85.5 Grandma Po ping. All right, so we know that the number most four paintings, 1.69 And for each of the pope in Mercury counting three, huh? Copping free carpet. So when we go back to our come on mass, most of what we need to know that I'm a mole of carbons. So we have free off the company in each other. Propane. So we have fully China's 1.64 So three times 1.6 sort 1.94 So we have five point eats you, um, more off carbons. Okay, so we're looking for the mass off carbons. So we have the lumber almost time to morning mass 65462 times and learn us off. Each hub in atom will be 12. So we have five points. Six sort, 5.82 times 12. We are a 69.84 gram off carbons info pay.
