Mass Percent: 4.476%, Element: Carbon The answer is 0.508gram The molecular mass for aspirin (C9H8O4) should be 180g/mol. normal_643b96b379f88.pdf It is appropriate to take into account a package of C9H8O4 and the use of its parasite mass (180.159 g/mol, developed . The aspirin molecule consists of 8 Hydrogen atom s , 9 Carbon atom s and 4 Oxygen atom s - a total of 21 atom s. Formula in Hill system is C9H8O4 Computing molar mass molar weight To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In some books, you may see the unit of molar mass as grams/mole or g/mole. Since there is a 2 right next to the O, you have to multiply the atomic mass [which you just found out to be 16] and multiply by two so O2 is 32. now add that to S's atomic mass [which you already know to be 32] and you get 64. that is the molar mass of SO2, What is the gram molecular mass (gmm) of chlorine, How many moles is each of the following: 15.5 g Sio2, How many moles is each of the following: 0.0688 g AgCl, How many moles is each of the following: 79.3 g Cl2, How many moles is each of the following: 5.96 g KOH, Find the mass of each substance: 1.50 mol C5H12, Find the mass of each substance: 14.4 mol F2, Find the mass of each substance: 0.780 mol Ca(CN)2, Find the mass of each substance: 7.00 mol H2O2, Find the mass of each substance: 5.60 mol NaOH, Calculate the volume of each of the following gases at STP: 7.6 mol Ar, Calculate the volume of each of the following gases at STP: 0.44 mol C2H6, Calculate the volume of each of the following gases at STP: 1.20 mol O2, What is the density of each of the following gases at STP: C3H8, What is the density of each of the following gases at STP: Ne, What is the density of each of the following gases at STP: NO2, Find each of the following quantities: A; the volume,in liters, of 835 g SO3 at STP, Find each of the following quantities: B; the mass, in grams,of a molecule of aspirin (C9H8O4), Find each of the following quantities: C; the number of atoms in 5.78 mol NH4NO3, Calculate the percent composition of each compound: H2S, Calculate the percent composition of each compound: (NH4)2C2O4, Calculate the percent composition of each compound: Mg(OH)2, Calculate the percent composition of each compound: Na3PO4, Calculate the number of grams of these elements: sulfur in 3.54 g H2S, Calculate the number of grams of these elements: nitrogen in 25.0 g(NH4)2C2O4, Calculate the number of grams of these elements: Magnesium in 97.4 g Mg(OH)2, Calculate the number of grams of these elements: Phosphorus in 804 g Na3PO4.
