The mole is widely used in chemistry as a convenient way to express amounts of reactants and products of chemical reactions for example, the chemical equation 2 h 2 + o 2 → 2h 2 o implies that 2 mol dihydrogen (h 2) and 1 mol dioxygen (o 2) react to form 2 mol water (h 2 o) the mole may also be used to represent the number of atoms, ions. Here's what i got the idea here is that the partial pressures of the three gases will depend on the mole fraction each gas has in the mixture - think dalton's law of partial pressures here more specifically, you can say that the partial pressure of a gas i that's part of a gaseous mixture that has a total pressure of p_'total will be equal. = 2528 grams kno 3 in 1 liter of water, now measure out 100 ml in another container (that's how i would do it) however if you wanted to create just 100 ml of the solution in total, just continue the math and divide by 10 to get to 100 ml instead of 1 liter = 2528 grams kno 3 what is the molarity of a solution made by dissolving 25 g of.
