Hi,
Answer: 30,2220 Hours
<u>My work:</u> There are 60 minutes in every hour and 8,760 hours in a year. To,easily achieve this problem you take 8,760 the hours in a year and multiply it with 34.5. (8,760 * 34.5) By doing this you get your answer of 302,220 Hours, or in minutes it would be 18,133,200 minutes.

There are two isotopes of uranium abundant in nature
U235 and U238
As given that the sample has average molar mass of 237.482 amu
Let the amount of U235 in 100g sample = x
the amount of U238 in 100 g sample = 100-x
the average molar mass = [235(x) + 238 (100-x)] / 100
237.482 = [235(x) + 238 (100-x)] / 100
237.482 X 100 = [235(x) + 238 (100-x)]
23748.2 = 235 x + 23800 - 238x
51.8 = 3x
x = 17.27 g
So percentage of U-235 = 17.27 %
The answer is (E). protons.
The atomic number of an atom is equal to the number of protons in the nucleus.
I hope this helped.
