Answer:
The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265
Explanation:
Mike Trout of the Los Angeles Angels has a contract worth $426,500,000
On the other side, you earn $100,000 per year.
To calculate the number of years it would take for you to earn what Mike Trout will earn from his contract, you must divide the amount Mike earned by the amount you earned during a year:
$426,500,000 ÷ $100,000 per year= 4,265
The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265
Molecular mass of C₂H₄ is,
M = 2×12 + 4×1 g/mol
M = 28 g/mol
Moles of C₂H₄ in 5.6 g of C₂H₄ :
n = 5.6/28 mol
n = 0.2 mol
Now, 1 mol of C₂H₄ contains 2 moles of carbon.
So, number of moles of carbon are :
n = 0.4 mol
We know, 1 mol of any atom contains 6.022 × 10²³ atoms.
So, number of carbon atoms are :
Hence, this is the required solution.
Make 2 in 102 as the power of 10
10^2 = 100
101 - 10^2 = 101 - 100 = 1
Hope it helped:)
