Answer:
Approximately , assuming that all sulfur in that coal was converted to
.
Explanation:
Look up the relative atomic mass of and
on a modern periodic table:
:
.
:
.
Convert the unit of the mass of coal to grams:
.
Mass of sulfur in that much coal:
.
The relative atomic mass of sulfur is . Therefore, the mass of each mole of sulfur atoms would be
. Calculate the number of moles of atoms in that
of sulfur:
.
Each molecule contains one sulfur atom. Therefore, assuming that all those (approximately)
of sulfur atoms were converted to
molecules through the reaction with
, (approximately)
of
molecules would be produced.
Calculate the mass of one mole of molecules:
.
The mass of that of
molecules would be:
.
Answer:
The answer to your question is: 2 grams of methane
Explanation:
Data
V = 9.15 l
P = 1.77 atm
T = 57° C = 330 °K
Ar mass = 19 g
CH4 mass = ?
Formula
PV = nRT
Process
n = 0.6
Argon
40 g of Ar -------------------- 1 mol
19 g --------------------- x
x = 0.475 mol of Ar
moles of CH4 = 0.6 - 0.475
= 0.125
Methane
16 g of CH4 --------------- 1mol
x ---------------- 0.125 mol
x = 2 grams
