Question

Butane, C reacts with Gyoen. O, to form water,H, and carbon dioxide, CO, as shown in the following chemical on: 2CH() +130,($)+10H,O() +SCO,() The coefficients in this equation represent molt s Notice that the coeficient for water (10) is vetimes that of butane (2). Thus the number of moles of water produced is five times the number of moles of butane that react Calculate the mass of water produced when 430g of butane reacts with excess open Express your answer to three significant figures and include the appropriate units View Available Hints P: + om? Also, notice that the coefficient for butane (2) is one-fourth the coefficient of carbon dioxide (8). Thus, the number of moles of butane that react is one fourth the number of moles of carbon dioxide that you produce But be carefullyou are given the mass of a compound, you must first convert to moles before applying these ratios. Value Units Suomi Part Calculate the mass of bure needed to produce 50.7 g of carbon dioxide Express your answer to three significant figures and include the appropriate unit
