Answer:
5.25 miles per minute
Step-by-step explanation:
420/80 = 5.25 so it is 5.25 miles per minute as it is 80 minutes
Step-by-step explanation:
120/20=6g
50/20=2.5g
170/20=8.5g
for one shortbread ^^
6*50=300g
2.5*50=125g
8.5*50=425g
for 50 shortbread ^^
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.
