Answer:
intersection point is (4,7)
Step-by-step explanation:
we have the equation y=x+3, and the point (4.0),
what point do the two lines intersect?
y=x+3, if x=4 then y=4+3 = 7; finally the intersection point is (4,7)

Formula of Trapezoid
Area= (b1+b2)/2*h
Area= (10+28)/2 * 23
Area= 38/2 * 23
Area= 19*23
= 437

8.2 grams = 1 mol
Na ________
22.99 grams
First multiply the value of 8.2 to 1. Then divide by the value of 22.99 to determine the number of moles of sodium present in the 8.2 gram sample.
Then use the following equation to solve for sodium atoms.
Number of moles of Na • Avogadro Number = Number of sodium atoms.
0.3566782 • (6.02 X 10^23). = 2.1472 X 10 ^ 23. Or 2.15 X 10 ^ 23.
The answer is the second option - 2.15 X 10 ^ 23.
