In a flask of volume v litres

WebA flask containing n moles of helium is being held at a temperature T Kelvins. If the volume of the flask is V liters, the pressure that the nRT gas exerts on the flask, in atmospheres, is given by P = where V R is a positive constant. WebJan 24, 2024 · This tells you that the solution is 70% isopropanol. The equation for volume percent is pretty straightforward: v v % = volume of solute volume of solution × 100. So, returning to our rubbing alcohol, 70% ( v v) means that for every 100 mL of solution, there are 70 mL of the solute, isopropanol. 70 % = volume of solute 100 mL × 100.
