Please help with question 2
2. Calculate the percent error if the true percent water in a popcorn kernel is 14.1%. 24.04-14.1 14.1 *100 = 70.5% Post Laboratory Questions 1. Why was the lid removed for cooling but replaced when massing? Think of what else the lid captures as the system is cooling. The lid was removed to let the Steam out. The lid Captures Condensation if not removed. 2. The process of dimensional analysis helps when the units get a bit more confusing. I am having you continue to practice this skill with the conversions defined below. Using YOUR average mass of water lost per kernel obtained in the experiment (pick either trial 1 or trial 2), calculate the number of grams of water per kernel of popcorn using dimensional analysis covered in topic 2. How many molecules of water is this? Show a t- chart. 1 mole = 6.022x1023 molecules 021g (water lost per Kernel) C 1 mole = 18.02 grams H₂O C In r 3. Determine the number of grams of water that is contained in 1.0 pound of unpopped corn. (1kg = 2.20 lbs) (Automatic conversions obtained from an online converter will not be awarded points.) It would be helpful to show a t-chart.
