W V Pg I. I = w / v or i = (w / r) 2. This is used when a solid chemical is. A percent w/v solution is calculated with the following formula using the gram as the base measure of weight (w):
Insert the number of amps (a) and volts (v) below and click on calculate to obtain watts (w). The formula is (a)* (v) = (w). David’s answer covers the definitions.
Used where both chemicals are liquids (e.g. It can alternatively be abbreviated to m/v for mass per volume. V = (w x r) 2 or v = w / i.
Identify the solute and solvent (by. For example, if you have a current of 2 a and a voltage of 5. V/v means volume/volume and is used when you mix 2 liquids together.
