Wait a second shoudl YOU do this one cause this is more of a YOU how am i suppose to know who you like?
i could give you a scientist just try albert Einstein
From the Graham's law of effusion;
R1/R2 = √MM2/√MM1
Molar mass of chlorine gas is 71
Therefore;
1.87= √ 71 /√mm1
= 1.87² = 71/mm1
mm1 = 71/1.87²
= 71/3.4969
= 20.3
Thus, the molar mass of the other gas is 20.3 , and i think the gas is neon
The best answer among the choices given is option A. Chemical weathering of rocks is a source of dissolved substances in the ocean.
