Answer:
0.0063mol
Explanation:
Number of moles (n) in a substance can be calculated by dividing the number of atoms (nA) of that substance by Avagadro's number i.e. 6.02 × 10^23. That is; n = nA ÷ 6.02 × 10^23
1 mol of Gold = 6.02 × 10^23 atoms
Therefore, 3.8 x 10^21 atoms of Gold will be;
3.8 x 10^21 ÷ 6.02 × 10^23
= 3.8 ÷ 6.02 × 10^ (21 - 23)
= 0.6312 × 10^-2
= 0.0063mol of Gold
I would go to cape coral to play basketball!
1. Wait to see if it is all clear and then go
2. Yield to those coming towards you and once it is totally clear then go.
3. Means you are able to go once you yield to oncoming traffic.
4. I don't remember.
5. Well honestly all the signs here are green so! but I would look to see if it says what restraunts there are or gas stations.
6. IDK
The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.
Answer:
To avoid variation due to concentration
