Accepted Answer

Hi everyone. So here we asked to identify the percentage by mass of carbon in calcium carbonate, recall that the mass percent is the mass of the element. If I buy the mass of the compound Times 100%,, so the mass percent of carbon, It's 12.011 divide by the mass of calcium carbonate. They have 40.07, 8 Plus 12. plus three, 15.999. We're gonna get 100 .09 g Times 100%. And this gives us 12%. Thanks for watching my video and I hope it was helpful.
