Answer: Mass of hydrogen produced is 0.0376 g.
Explanation:
The reaction equation will be as follows.
Now, formula for total pressure will be as follows.
Hence, 
= 755 mm Hg - 42.23 mm Hg
= 712.77 mm Hg
= 0.937 atm
Now, we will calculate the moles of 
as follows.
n = 
mol
= 0.0187 mol
Therefore, mass of will be calculated as follows.
= 0.0376 g
Thus, we can conclude that mass of hydrogen produced is 0.0376 g.

Answer:
820.864 g
Explanation:
1) The atomic mass of sulfur (found from the periodic table) is 32.065 amu. Use this mass to find the molar mass of Sulfur. Sulfur is S8 so the molar mass of sulfur is:
8 × 32.065 = 256.52 g/mol
2) To find the mass use the formula:
m = n × M where <em>m</em><em> </em>is the mass, <em>n</em><em> </em>is the number of moles, and <em>M</em><em> </em>is the molar mass.
3)
Answer:
1.04 moles of AlCl₃
Explanation:
Balanced Equation: 2Al°(s) + 3Cl₂(g) => 2AlCl₃(s)
Approach => convert given data (28 g Al°) to moles. The number of moles AlCl₃ would equal the number of moles aluminum because coefficients for Aluminum and Aluminum Chloride are equal.
moles Al° = (28g)/(27g/mole ) = 1.04 mole Al°
From balanced equation moles AlCl₃ produced equals moles of Al° produced = 1.04 mole AlCl₃ because coefficients of Al° & AlCl₃.
