Hi, so to solve for this, we're solving for the percent composition of the elements in saccharine.
00:10
So percent carbon, we know that the atomic mass of carbon is 12 .01, and then in saccharine we have seven carbons, so we'll multiply this by seven, and then divided by the atomic mass or molar mass of saccharine, that's 183 .20, and then we'll multiply 100 percent, calculating this one, we'll have 45 .89 percent.
00:36
Okay, next one, we have hydrogen.
00:42
So atomic mass of hydrogen is 1 .01, and we have five hydrogens in the molecular formula of saccharine, so multiply this by five, divided by the molar mass 183 .20, multiply this by 100 percent, and we'll get 2 .76 percent...
