The mass of the air in the room is
50 kg.
V = lwh = 15.5 ft × 12.5 ft × 8 ft = 1550 ft³
1 ft = 12 in ×
= 30.48 cm
V = 1550 ft³ ×
= 4.39 × 10⁷ cm ³ = 4.39 × 10⁷mL = 4.39 × 10⁴ L
Mass = 4.39 × 10⁴ L ×
= 5.22 × 10⁴ g = 52.2 kg
Note: The answer can have only 1 significant figure, because that is all you gave for the height of the room.
To the correct number of significant figures, the mass of the air in the room is 50 kg.
If more reactant is added, the equation will shift to the right in order to make more product (which will increase the products)
Answer:
Henry Moseley
Explanation:
Dmitry Mendeleef and Lothar Meyer proposed a periodic table based on the atomic mass.
They stated a periodic law expressed as "chemical properties of elements are a periodic function of their atomic weights".
But, Henry Moseley in 1900s re-stated periodic law by changing the basis of the law from atomic weight to atomic number.
The present periodic law is stated as "the properties of elements are a periodic function of their atomic number".
The mass of oxygen reacted/required in this reaction is obtained as 48g.
<h3>What is stoichiometry?</h3>
The term stoichiometry has to do with mass- volume or mass - mole relationship which ultimately depends on the balanced reaction equation.
Now, we have the reaction; S + O2 ------>SO2
If 1 mole of sulfur dioxide contains 22.4 L
x moles of sulfur dioxide contains 33.6L
x = 1.5 moles of sulfur dioxide.
Since the reaction is 1:1, the number if moles of oxygen required/reacted is 1.5 moles.
Mass of oxygen required/reacted = 1.5 moles * 32 g/mol = 48g
