Answer:
32.8g/mole
Explanation:
Given parameters:
Mass of sample of gas = 32.8g
Volume = 22.4L
Unknown:
Molecular weight = ?
Solution:
To solve this problem we must understand that at rtp;
1 mole of gas occupies a volume of 22.4L
Number of mole of the gas = 1 mole
Now;
Mass = number of moles x molecular weight
molecular weight =
=
= 32.8g/mole
The Actinide series contains elements with atomic #'s 89 to 103 and is the sixth group in the periodic table. This series is below the Lanthanide series, which is located under the main body of the periodic table. Both Actinide and Lanthanide series are refered to as Rare Earth Metals. Hope this helped
