Explanation:
Answer:
The car travel 660 feet
Explanation:
First convert the Speed into <u>Feet/sec</u>
Speed of the car = 90 mi/hr
1 mi = 5280 ft
In 90 miles = 90 x 5280 = 475,200 feet
1 hr = 60 min
1 min = 60 sec
So ,
1 hr = 60 x 60 sec = 3600 sec
The speed is defined as the distance traveled by the object in unit time. The formula of speed is :
... given
Speed = 132 ft/sec
Now, time = 5 sec
Distance = 660 feet
Answer:
3.45 moles Li contains 2.08 × 10 (to the power of)24 atoms .
Explanation:
The relationship between atoms and moles is:
1 mole atoms =
6.022 × 10 (to the power of)23
atoms
In order to determine how many atoms occupy a given number of moles, multiply the given moles by
6.022 × 10 (to the power of)23
atoms/mole
.
In the case of 3.45 moles lithium (Li):
3.45 mol Li × 6.022 × 10 (to the power of)23 atoms Li/ 1 mol Li =
2.08 × 10 (to the power of)24
atoms Li rounded to three
