Answer:
Light energy is converted into chemical energy.
Answer:
Liters
Explanation:
Just like meters, liters is used to calculate large volumes of liquid, not solids. :) I hope this helped!

The molarity of the solution is 0.260 M
<u><em>calculation</em></u>
step 1: calculate the moles of NaOH
moles = mass÷ molar mas
= 5.20 g÷ 40.00 g/mol= 0.13 moles
Step 2: find the molarity of solution
molarity = moles÷volume in liters
=0.13 moles÷ 0.500 L = 0.260 M
Answer:
1425 mmHg.
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 1.5 L
Initial pressure (P1) = 1 atm
Final volume (V2) = 0.8 L
Final pressure (P2) =?
Next, we shall determine the final pressure of the gas by using the Boyle's law equation as follow:
P1V1 = P2V2
1 × 1.5 = P2 × 0.8
1.5 = P2 × 0.8
Divide both side by 0.8
P2 = 1.5/0.8
P2 = 1.875 atm
Finally, we shall convert 1.875 atm to mmHg.
This can be obtained as follow:
1 atm = 760 mmHg
Therefore,
1.875 atm = 1.875 × 760 = 1425 mmHg.
Therefore, the new pressure of the gas is 1425 mmHg.
