Answer:
1. 203.976amu
2. 43.991amu
3. 334.36amu
Step-by-step explanation:
Find a period table with the atomic mass units.
1 Hydrogen = 1.008amu
1 Carbon = 12.011amu
1 Oxygen =15.99amu
1 Nitrogen = 14.007amu
1 Sulfur = 32.066amu
Plugin for each equation
1. Sugar
6 C • 12.011amu = 72.066
12 H • 1.008amu = 12.096
6 O • 15.99amu =95.94
Add all together to get total amu (atomic mass units) for Sugar (6C12H6O)
95.94amu + 12.096 amu + 72.066amu = 203.976amu
2. Carbon Dioxide
1 C • 12.011amu = 12.011amu
2 O • 15.99amu = 31.98amu
12.011amu + 31.98 amu = 43.991amu
3. Penicillin
16 C • 12.011amu = 192.176amu
18 H • 1.008amu = 18.144amu
2 N • 14.007 = 28.014amu
4 O • 15.99amu = 63.96amu
1 S • 32.066 = 32.066amu
192.176amu+18.144amu+28.014amu+63.96amu+32.066amu = 334.36amu
37.5% as a fraction is 3/8.
Answer:
300 cm
Step-by-step explanation:
area of rectangel = 5 × 11
area of rectangle = 55 cm
area of circle = π r²
area of circle = 3,14 × 12 × 12
area of circle = 452,16 cm
area of the shaded region
= 452 - 55
= 297 cm
Round your final answer to the nearest hundredth
= 300 cm
16 is 8% of 200
Let me know if that's good
Answer:
B
Step-by-step explanation:
Plug in coordinates to see if they match the answer.
It's easier in slope-intercept form, so lets change it first.
-2x+y=7
+2x +2x
y=2x+7
Now we can plug in the coordinates to see if they match.
Lets try A.
11=2(-2)+7
11=-4+7
11=3
A is incorrect.
Lets try B.
11=2(2)+7
11=4+7
11=11
B is a solution, therefore is on the graph.
