when a large object fell into a "full" swimming pool, it displaced 35.1 gallons of water. The density of the object is 1.65 g/mL
1 answer:
Answer:
m = 483.32 pounds
Explanation:
Given that,
The density of the object is 1.65 g/mL
Volume of the water is 35.1 gallons
We know that,
1 gallon = 3785.41 mL
35.1 gallons = 132868 mL
The density of an object is equal to its mass divided by its volume. So,
Also, 1 pound = 453.592 grams
So, 219232.2 grams = 483.32 pounds
So, the weight of the object is 483.32 pounds.

Diffusion is the process of a substance spreading out to evenly fill its container or environment. Rate of diffusion of a gas is inversely proportional to the molar mass of the gas.
Lighter(lower) the molar mass of the gas , faster will be its rate of diffusion and heavier (higher) the molar mass of the gas , slower will be its rate of diffusion.
We have to arrange the given gases from slowest rate of diffusion to fastest rate of diffusion that means we need to arrange gases from higher molar mass to lower molar mass.
Molar mass of given gases are :
Cl = 35.5 g/mol
Xe = 131.29 g/mol
He = 4.00 g/mol
N = 14.00 g/mol
So correct order for slowest rate of diffusion (highest molar mass) to fastest rate of diffusion (lowest molar mass) is :
Xe , Cl , N , He
Xe having the highest molar mass will have the slowest rate of diffusion and He with lowest molar mass will have the fastest rate of diffusion, so option 'c' is correct.
Note : Slowest rate of diffusion = High Molar Mass
Fastest rate of diffusion = Low Molar Mass
