A chemist mixes 18.0 g of ethanol with 61.0 g of thiophene and 27.0 g of methanol. Calculate the percent by mass of each component of this solution. Be sure each of your answer entries has the correct number of significant digits. | Component | Mass Percent | |------------|---------------| | Ethanol | % | | Thiophene | % | | Methanol | % | There is an input area for each mass percent value. To the right, there is a small panel with icons for numerical operations: a checkbox with "x10" for multiplying by ten, an "X" for clearing or deleting, a curved arrow for resetting, and a question mark for help or hints.
