 Click here to see ALL problems on Miscellaneous Word Problems Question 185582: The mass of a molecule of a certain chemical compound is 2.45*10 to the power of -22 g. If each molecule is made up of two carbon atoms and six oxygen atoms and the mass of one oxygen atom is 1/3 that of a carbon atom, find the mass of an oxygen atom. The answer is 2.04 * 10 to the power of -23 g. I do not understand this in terms of showing working.Answer by edjones(7569)   (Show Source): You can put this solution on YOUR website!Let c=carbon & g=oxygen 2c+6/3g=2.45*10^-22 2c+2g=2.45*10^-22 there are equal masses of oxygen and carbon in the compound. 0.5*2.45*10^-22 =1.225*10^-22 mass of oxygen in the compound. (1/6)*1.225*10^-22 There were 6 oxygen atoms in the compound =.2041667...*10^-22 =2.04...*10^-23 Mass of oxygen. . Ed
