For f11 in the homework, when converting the mass percentages into its mass percentage in grams, how exactly can I convert it?

Hello danny ! Well this is quite simple actually, you probably missed the example showing how to do this process; if the mass percentage is 65.5% the the mass percentage into grams is simply 65.5g , it is exactly the percentage without the % symbol, hope thats helpful !!!

Just think of converting percent to mass like the formula for mass percentage. (Molar Mass of a specific element/ mass of entire compound) x 100% which explains why when you were given 50% C you convert that to 50g since you multiply by 100%.

I hope this helps. Correct me if I am wrong in my explanation.

Hey just to add on when it gives you a mass percentage the easiest way to interpret that is to assume that there is a 100g sample of whatever you are trying to analyze. So for this example you basically just find the molar ratios using a 100g sample. Let me know if you need anything else!
