Questions and Videos on Dilution Calculations, within Chemistry

Substitute these values into the equation and if the left side equals the right side then they are the solutions. ∙ x = 5 → 5 −3 = √5 − 1 → 2 = 2 ⇒ a solution

Here's my take on this. Assuming that the question is not incomplete, your goal here is to figure out the dilution factor, "DF", for the second dilution, and the overall dilution factor for the two …

It's worth knowing that the dilution factor, DF, tells you the ratio that exists between the volume of the diluted solution and the volume of the stock solution. DF = V diluted V stock In your case, …

I think it's a trick question... each of these is an equation for a line in the form y = mx + b , where m is the slope of the line. m is given as 2 in each of the equations. They have the slope, …

Well this one is easy; of course there is a catch..... When you work with concentrated acids, you ALWAYS add acid to water and never the reverse. This is non-negotiable and it is absolutely …

Here's what I got. For part (A), calcium carbonate, "CaCO"_3, which is insoluble in water, will be dissolved in hydrochloric acid, "HCl", to form aqueous calcium ...

The equation a^2+b^2=c^2 is Pythogoras' Theorem, otherwise known as the Pythagorean theorem and it is used to find the missing side of right and angled triangles. The longest side, …

Here's how you can do that. A solution's concentration in parts per million, or ppm, tells you the number of grams of solute you get for every 10^6 = 1,000,000 grams of solution. Similarly, a …

We want the standard enthalpy of formation for Ca (OH)_2. Thus, our required equation is the equation where all the constituent elements combine to form the compound, i.e.: Ca …
