- Nuclear energy comes from splitting atoms in a reactor to heat water into steam, turn a turbine and generate electricity.
- Nuclear reactions are used to release nuclear energy that generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant.
- Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.
- Nuclear energy may be used in a wide variety of fields as it generates high levels of electricity without causing damage to our environment and atmosphere.
Answer:
1.5x 10^24
Explanation:
for every 1 mol there are 6.02 x 10^23 molecules
2.5 mol x 6.02 x 10^23
-----------------
1 mol
The density of a pure gold is 19.32g/cm3
if the volume is 4.30 cm3 then we can calculate the mass using the formula mass=density x volume
mass=19.32*4.30
mass=83.076g
<span>Well if you're looking for grams, all you need to do is cancel out units.
(ml)(g/ml)=g because the ml cancels out.
Thus, multiply: (85.32ml)(1.03g/ml)=...I'll let you solve this. :)
Good luck! Hope that helped. When in doubt, look at the units.</span>
