50 g of iron, 5 g atoms of hydrogen, 0.1g atoms of silver, 10^23 atoms of carbon

Answer 1

206 gm of Ba.(A=137.3, Z="56)"2. 415.45 gm of Sn(A=118,Z=50)3. 11.45 g of Zn(A=65,Z=30)4. 80 g of S8 (A=32 ,Z=16)Solution:1. Atomic weight of Ba = 137.3 gmole concept problems

Introduction to mole concept problemsFind the number of gram atoms of the elements contained in each of the following:1. 206 gm of Ba.(A=137.3, Z="56)"2. 415.45 gm of Sn(A=118,Z=50)3. 11.45 g of Zn(A=65,Z=30)4. 80 g of S8 (A=32 ,Z=16)Solution:1. Atomic weight of Ba = 137.3 g137.3 gm equals to 1 g of atom206g.....................>?= 206/137.3= 1.5g atoms2. Atomic weight of Sn = 11848 g equals to 1 gm atom415.4 gm =?= 415.4/118= 3.5g atoms3. Atomic weight of Zn = 6565 g equals to 1 gm of tom114.5 gm = ?= 114.5/65= 17.6 g atoms4. Atomic weight of S="32"32gm equals to 1 g atom80g = ?=80/32= 2.5g of atomsQuestion:
