Explanation:
0.2g of atom of nitrogen is the one that weigh least cause of.2g is not up to one mole of nitrogen
Answer:
I think 767.8
Explanation:
I first did 10 times 22 bc that little carrot sign means squared so I did 10 times 22 and that equaled 220, then I did 3.49 times 220 and that is the answer which is 767.8
The time taken for Hydrogen-3 to decay from 88 g to 11 g is 36.9 years.
<h3>Half-life:</h3>
This can be defined as the time taken for half the sample of a substance to decay or disintegrate
To calculate the time it will take Hydrogen to decay from 88g to 11 g we use the formula below.
Formula:
- R = R'(
)................ Equation 1
Where:
- R = Original sample of Hydrogen
- R' = Sample of Hydrogen left after decay
- T = Total time of decay
- n = Half-life of hydrogen.
From the question,
Given:
- R = 88 g
- R' = 11 g
- n = 12.3 years.
Substitute these values into equation 1
- 88 = 11(
)
Solve for T.
= 88/11
= 8
= 2³................ Equation 2
Equating the base in equation 2 above,
- T/12.3 = 3
- T = 12.3×3
- T = 36.9 years.
Hence, the time taken for Hydrogen-3 to decay from 88 g to 11 g is 36.9 years
