How many 200 ml glasses can you fill if you have 1 liter?
5 obviously. 1L=1000ml 200x5=1000ml
What is the molarity of a solution with 5 moles of lithium flouride dissolved in 200 mL of water?
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.
How many kw in five hours does 10 20 watt 12 volt lights use?
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.
How many ml of 1 M stock solution of Na Cl are needed to prepare 200 ml of a 0.05 M solution?
To prepare a 0.05 M solution of NaCl in 200 ml, you would need 2 ml of the 1 M stock solution. This is calculated using the formula: (C1V1) = (C2V2), where C1 is the concentration of the stock solution, V1 is the volume of the stock solution needed, C2 is the desired concentration, and V2 is the final volume of the solution.
