We are asked to calculate for the** percent by mass (mass %) of O in ****digitoxin, C _{41}H_{64}O**

_{13}

_{ }and to do that we’re going to use the

**mass percent formula**shown below:

$\overline{){\mathbf{mass}}{\mathbf{}}{\mathbf{percent}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{mass}\mathbf{}\mathbf{element}}{\mathbf{total}\mathbf{}\mathbf{mass}\mathbf{}\mathbf{of}\mathbf{}\mathbf{compound}}{\mathbf{\times}}{\mathbf{100}}}$

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

$\overline{){\mathbf{\%}}{\mathbf{}}{\mathbf{mass}}{\mathbf{}}{\mathbf{O}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{mass}\mathbf{}\mathbf{O}}{\mathbf{mass}\mathbf{}{\mathbf{C}}_{\mathbf{41}}{\mathbf{H}}_{\mathbf{64}}{\mathbf{O}}_{\mathbf{13}}}{\mathbf{\times}}{\mathbf{100}}}$

*We will do the following steps to solve the problem:*

*Step 1: Calculate the mass of O in 1 mol of C _{41}H_{64}O_{13}*

*Step 2: Calculate the mass of 1 mol of C _{41}H_{64}O_{13}*

*Step 3: Calculate the percent by mass of O in **digitoxin, C _{41}H_{64}O*

_{13}
