Problem: To calculate Zn density as the following experiment
Empty flask weight is 36.2142 grams
Experiment 1: Pour water into Flask and weigh, total weight is 46.1894 grams
Step1: Put Zn powder into empty flask and weigh, total weight is 38.1055 grams
Step 2: Pour water into Flask that contained Zn powder and weigh, total weight is 47.8141 grams
What is Zn density?
Should I minus like this : 47.8141 - 46.1894 and Divide by Zn weight (38.1055 -36.2142)??
Can anyone guide me to solve this?
