1.000.000 is the correct answer
To determine what elements are represented by the electron configuration given above, we need to know the sum of the exponents of each term or subshell involved in the configuration as this represent the atomic number of the element.
Atomic Number Element
<span>1s2 2s2 2p6: 2 + 2 + 6 = 10 neon
1s2 2s2 2p6 3s2 3p3: </span>2 + 2 + 6 + 2 + 3 = <span>15 phosphorus
1s2 2s2 2p6 3s2 3p6 4s1: </span>2 + 2 + 6 + 2 + 6+1 = <span>19 potassium
1s2 2s2 2p6 3s2 3p6 4s2 3d8: 20 + 8 = 28 nickel
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d3: 30 + 6 + 2 +3 = 41 niobium</span>
The percentage yield of the product if the actual yield was measured as 2.80 g and the theoretical yield is measured as 3.12 g is 11.43%.
<h3>How to calculate percentage yield?</h3>
The percentage yield of a substance can be calculated by dividing the difference between the actual and theoretical yield by the actual yield, then multiplied by 100.
Percentage yield = (theoretical yield - actual yield)/actual yield × 100
According to this question, the actual yield of a product in a reaction was measured as 2.80 and the theoretical yield of the product for the reaction is 3.12 g.
Percent yield = (3.12g - 2.80g)/2.80 × 100
Percent yield = 11.43%.
Therefore, percentage yield of the product if the actual yield was measured as 2.80 g and the theoretical yield is measured as 3.12 g is 11.43%.
