Students are tasked with calculating the amount of sodium gas (NaN 3) that must be produced to inflate a vehicle air bag to the correct size . According to the balanced chemical equation, 6 mol of CO2 is produced per mole of glucose; the mole ratio of CO2 to glucose is therefore 6:1. Now lets use equation 1 and multiply each side by "1 gram (s)" as we can do in algebra. >> The notebook incl. It walks through each conversion with more detail. Units . We assume you are converting between gram [sugar] and gram [water].You can view more details on each measurement unit: grams or gram The SI derived unit for volume is the cubic meter. Sometimes an immutable group in chemical compounds is replaced with a fictitious element to balance the equation, which otherwise can not be uniquely balanced. The number of moles of CO2 produced is thus, \[ moles \, CO_2 = mol \, glucose \times {6 \, mol \, CO_2 \over 1 \, mol \, glucose } \nonumber \], \[ = 0.251 \, mol \, glucose \times {6 \, mol \, CO_2 \over 1 \, mol \, glucose } \nonumber \]. In a similar way, chemists study the proportion of substances in reactions to find out how they interact with each other. Specifically, between the reactants and products in chemical reactions. help them set up the problems. This website uses cookies to improve your experience while you navigate through the website.
