Answer:
A catalytic converter is a device used to reduce the emissions from an internal combustion engine (used in most modern day automobiles and vehicles). Not enough oxygen is available to oxidize the carbon fuel in these engines completely into carbon dioxide and water; thus toxic by-products are produced. Catalytic converters are used in exhaust systems to provide a site for the oxidation and reduction of toxic by-products (like nitrogen oxides, carbon monoxide, and hydrocarbons) of fuel into less hazardous substances such as carbon dioxide, water vapor, and nitrogen gas.
The mass of the N₂O in the given question is 92.4g.
<h3>What is the moles of N2O in the given conditions?</h3>
STEP1- Apply the ideal gas equation
PV=nRT
STEP2- Put the given values in the equation
P=130kPa, T=298K, V=40L R=8.31
STEP3- Solve the equation
N=PV/RT,
N=130×40/8.31×298
N=2.1moles
N=mass/molecular mass
mass=2.1×44
mass = 92.4g
Hence, the mass of N₂O is 92.4g.

Answer:
<h2>3.18 × 10²³ atoms</h2>
Explanation:
The number of atoms can be found by using the formula
N = n × L
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 0.529 × 6.02 × 10²³
We have the final answer as
<h3>3.18 × 10²³ atoms</h3>
Hope this helps you
Answer:
0.20 mol's
Explanation:
1.675 L = 1.675 dm^3
moles = V/(conc):
moles = 1.675/(8.5)
moles = 0.1970... --> 0.20
