Problem: Calculate the percentage by mass of oxygen in the following compounds.digitoxin, C41H64O13

FREE Expert Solution

We are asked to calculate for the percent by mass (mass %) of O in digitoxin, C41H64O13 and to do that we’re going to use the mass percent formula shown below:

mass percent = mass elementtotal mass of compound×100


For the percent by mass C, we’re going to rewrite the equation as:

% mass C = mass Cmass C41H64O13×100


We will do the following steps to solve the problem:

Step 1: Calculate the mass of 1 mole of C

Step 2: Calculate the mass of 1 mole of digitoxin, C41H64O13

Step 3: Calculate the percent by mass of C in digitoxin, C41H64O13
