Answer:
29.07778262 (i don't know what you have to round to, but just be aware of rounding)
Explanation:
to answer this you have to convert both elements into grams, you do this by finding their atomic weight on a periodic table then multiplying it by how many moles of the molecule you have, k=39.098 and S=32.06, so you have to multiply k by two since you have two moles, so now you know that k2=78.196. then add the two amounts together to get the total weight of the compound, 110.256, now that you have that you can create a proportion to solve for the percent, the proportion is equal to the mass of one element, in this case S, over the total weight of the compound, 110.256. then divide [tex]\frac{32.06}{110.256}[/tex] =.290777... this is your percent in decimal form, so multiply by 100 to get you percentage.
