How many grams of neon gas should be placed into a 10.0 L container in order for it to meet STP conditions?
12.2 g
9.00 g
0.00441g
122 g

Answer 1

9.0 grams because the atomic mass of 1 mole of Neon STP(22.4L) is 20.17 and cross multiply 10.0g(given) by the 20.17, and divide by 22.4L to get 9.00 grams of Neon to match 10L container at STP

Answer 2

9.0 g
