Question 34 How many grams of oxygen (O) are present in a 6.35 g sample of potassium nitrate (KNO3)? Enter your answer in decimal form with the correct number of sig figs. Use the proper abbreviation for the units. NOTE: If you have taken chemistry before and know what diatomic means, do not take that into consideration. Use just O for this. There are reasons for this. Your Answer: Answer units
Calculating and using the molar mass of diatomic elements A chemist measures the amount of iodine solid produced during an experiment. He finds that 49.1 g of iodine solid is produced. Calculate the number of moles of lodine solid produced. Be sure your answer has the correct number of significant digits. mol Explanation Check 0 X S v Graw Hill LLC. All Rights Reserved.
