6 0

Answer: 4.52x10²⁴ atoms Li

Explanation: For 1 mole of Li it is equal to the Avogadro's Number.

Solution:

7.5 moles Li x 6.022x10²³ atoms Li/ 1 mole Li

= 4.52x10²⁴ atoms Li

The distance from the surface of the earth to the moon is approximately 3.8 * 10 to the 5th km. How many days would a distance l
Alla [95]

Answer:

82 days would take a distance like that, if we drive at 120 mi/h

Explanation:

Distance from Earth to moon is 3.8×10⁵ km

You drive at a speed of 120 mi/h

Let's convert the 120 mi/h to km/h

1 mi = 1.61 km

Then 120 mi . 1.61 km / 1mi = 193.2 km

New velocity is 193.2 km. Therefore,

193.2 km are driven in 1 hour

3.8×10⁵ km woul be driven in (3.8×10⁵ . 1)/ 193.2 = 1966.8 hours

1967 hours . 1 day / 24 hours = 82 days

6.285×10^3 mg = _____? _____ kg
TiliK225 [7]
One kilogram is equal to one thousand grams. Further, one gram is equal to 1000 mg. The conversion is as shown below,
                    (6.285 x 10³ mg) x (1 g / 1000 mg) x (1 kg / 1000 g)
The numerical value of the operation above is 0.006285 kg.
