# How many moles of Na-OH are needed to prepare 1.00L of a 0.5 M solution?

678

The molarity is figured out by the number of moles of NaOH over the number of liters of water. so if the molarity is 0.5M and there is 1.0L of water then there has to be 0.5 moles of NaOH in the solution.

A Hectoliter = 100L A Kiloliter = 1000L 1000L/100L = 10 Hectoliters per kiloliter  15g in 100L is 0.15g/ litre. The molecular weight of NaOH is 40g/mol. 0.15/40 is .00375 molar. 100L : FRAME MEANS 100mm is the height of the Center of the Motor shaft from it's base. If i'm wrong, please let me know phani_raj@rediffmail.com     It is one hundreth of a liter. In other words 1/100L. A litre is 10cm x 10cm x 10cm so it's 0.001 cubic metres. That means 100L will be 0.1 cubic metres. That's the same as 6102 cubic inches or 3.53 cubic feet. Another way to look at this is: 100L = 100*1000mL. 1mL = 1cc (cubic centimeter). Thus, 100L = 100*1000cc = 100 cubic decimeter = 0.1 cubic meter. 1in = 2.54cm. 1 cubic inch = 2.54^3 cc. So 100L = 10^5 / 2.54^3 cubic inches = 6102.37 cubic in. 1 cubic feet = 12^3 cubic inch. Therefore, 100L = 6102.37/12^3 cubic feet = 3.53147 cubic ft.     This mainly depends on pressure and temperature (not mentioned in this question)The gas density at STP (0 &deg;C and 101.325 kPa) is 0.08988 g,so 100L hydrogen gas at 0 &deg;C and 101.325 kPaweighs 8.988 g He/she stores the water in the lining of the stomach in sacs, which turns into fat and it goes into its blood stream after 100L of water. The universal gas equation is PV = nRT (Pressure x Volume = Number of moles x Universal Gas Constant x Temperature in Kelvin/Rankin). So - if Pressure is constant, the number of moles is constant, but the temperature increases from 25C (298 K) to 125C (398K) - a 34% increase, a similar 34% increase in volume will occur. 100 liters = 22.00 Imperial gallons = 26.42 US gallons.100L is 26.4 US gallons. that question is easy, just train them! it takes a lot of time so be patient. you can also give them rare candies  Approximately 270ml per day. In a whole year our feet produce 100L. Under good sun-light and temperature you can get 1000L for 100L of culture in about a week. Growth is logarithmic. Cheers, Boris. Camel can drink 100L at a timeThey can do this as they can survive without water for hours and hours however they do need food,Camels need 3.5 Kilograms of food each day.wow
