Consider 100 moles of a gas stream containing 15 mol% CS2, 18 mol% O2, and 67 mol% N2. The gas is fed to a continuous absorption tower, where it contacts liquid benzene, which absorbs CS2, but not O2 or N2. Benzene is fed to a column in a 2:1 mole ratio to the feed gas. Some of the benzene entering as liquid evaporates and leaves the top of the tower as vapor. The gas leaving the absorber contains 2 mol% CS2 and 2 mol% benzene. How many independent material balances can you write

answer: i dont know the answer but this might

explanation:

l

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
