Answer:
26,167.47m
Explanation:
Problem:
We are to solve this problem using dimensional analysis:
from the given conversion factors-
0.621mi = 1.00km
1km = 1000m
From the problem, we are groing from miles to metres:
16.25mi x 
x 
The mi will cancel out and also the km. This leaves us with the desired unit we want which is meters, m.
= 26,167.47m
C. Electrical conductivity, that means it can pass electricity through wires if needed, think of your phone charger as an example
Answer:
183 cg = 0.00183 kg

Answer:
<h2>0.05 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>0.05 moles</h3>
