A 0.600 g sample of a compound was found to contain 0.454 g of arsenic and 0.146 g of oxygen. What is the empirical formula of the compound? Hint: This time you are given gram amounts. Use those instead of assuming 100. grams. Otherwise, the process is the same. Hint 2: Remember that subscripts must be whole number. You may need to multiply by a common factor to get whole number values.
