200 multiplied by 5 equals 1000.
5 obviously. 1L=1000ml 200x5=1000ml
The molarity of the solution is calculated by dividing the number of moles of solute by the volume of the solution in liters. In this case, 5 moles of lithium fluoride in 200 mL (or 0.2 L) of water gives a molarity of 25 M.
To calculate the energy consumption in kilowatt-hours (kWh), you need to convert the wattage to kilowatts and then multiply by the number of hours. Each light uses 20 watts, so 20 watts = 0.02 kW. With 10 lights running for 5 hours, the total energy consumption would be 10 lights * 0.02 kW * 5 hours = 1 kWh.
Molartiy = moles of solute/Liters of solution200 mL X (1 Liter/10^2)= 0.200 Liters0.200 Liters x (0.05 M)= .01 moles of NaOH.01 moles of NaOH x (40 g NaOH/ 1 mole NaOH)= 0.4 g NaOH are required
