Answer:
0.13 s
Explanation:
We'll begin by converting 24900 mile to metres (m). This can be obtained as follow:
1 mile = 1609.344 m
Therefore,
24900 mile = 24900 mile × 1609.344 m / 1 mile
24900 mile = 4.01×10⁷ m
Finally, we shall determine the time taken for light to circumnavigate the Earth, this can be obtained as follow:
Distance = 4.01×10⁷ m
Speed = 2.998×10⁸ m/s
Time =?
Speed = distance / time
2.998×10⁸ = 4.01×10⁷ / time
Cross multiply
2.998×10⁸ × time = 4.01×10⁷
Divide both side by 2.998×10⁸
Time = 4.01×10⁷ / 2.998×10⁸
Time = 0.13 s
Thus, it will take 0.13 s for light to circumnavigate the Earth.
Answer:
Explanation:
= Density of acetic acid = 
= Mass of acetic acid = 
= Volume
Density is given by
The volume of acetic acid is .
You're going to divide the mass of chlorine within the compound by the mass of the compound, and then multiply the result by 100 to get the answer
