WebHow many moles of sodium hydroxide are in 20.0 mL of a 0.50 M #NaOH# solution? How many moles of solute are present in 1.25 L of a 0.75 M #NaNO_3# solution? 734 mL of a 1.13 M calcium sulfate (#CaSO_4#) solution is diluted with 2.56 L of water. WebI believe you're correct. There was likely a typographic error in the example. We see in the previous step the conversion was done correctly (50 mL = .050 L) so we have 0.02401 … reframe sliding glass shower doot

Water moles to volume & weight calculation - Aqua-Calc

Web5 okt. 2013 · When different volumes of an identical solution are added together, the final volume will always be exactly the sum of the individual portions added. For example, adding 50 mL of water to 50 mL of water will result in a total volume of 100 mL, and adding 75 mL of 100% ethanol to 75 mL of 100% ethanol will result in a total volume of 150 mL. Web14 nov. 2011 · How to convert a volume into an amount in moles. You need the concentration of the solution to do this. n = CV.
