Answer:
Explanation:
We have to remember the <u>molarity equation</u>:
So, we have to calculate "mol" and "L". The total volume is 100 mL. So, we can do the <u>conversion</u>:
Now we can calculate the moles. For this we have to calculate the <u>molar mass</u>:
O: 16 g/mol
H: 1 g/mol
C: 12 g/mol
With the molar mass value we can <u>calculate the number of moles</u>:
Finally, we can <u>calculate the molarity</u>:
I hope it helps!
So it’s OKAYYYYY ITS OKAYYYY

<h3><u>Answer;</u></h3>
Hydroelectric power
<h3><u>Explanation</u>;</h3>
- Hydroelectric power is produced when a turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.
- Hydroelectric power plants uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
