* First! Figure out what pyridine's formula is: C5H5N So, we know that each molecule of pyridine has 5 C, 5 H, and 1 N. The cool thing about the formula is it doesn't matter what the unit is, as long as the ratio between the C, H, and N remains the same, BUT, being that we're doing chemistry let's use moles. :) 5 moles of C + 5 moles of H + 1 mole of N -->1 mole of C5H5N This can be a weird concept, because you might think "how do you put in 11 moles of stuff and get only one mole of product"... but, just like baking, you put in 5 cups of sugar, 5 cups of flour, and 1 cup of butter, but get one really big cookie (didn't say it would be a good cookie). Well, you put in a few moles of this, a few moles of that...and you get a single mole of C5H5N. * After you figure out the chemical formula, calculate molecular mass: 5 moles of carbon = 5 x 12.011 grams per mole = 60.055 grams 5 moles of hyrdrogen = 5 x 1.008 grams per mole= 5.04 grams 1 mole of nitrogen = 1 x 14.007 grams per mole= 14.007 grams ADD: 60.055 + 5.04 + 14.007 = 79.102 grams per 1 mole of C5H5N * Convert solute to moles! Now, we've figured out that 1 mole of C5H5N has a mass of 79.102 grams....but, we're only putting 5 grams in the solution. How many moles is 5 grams if 1 mole is 79.102 grams? Calculate: 5 grams/ 79.102 grams = .063 moles * Convert to moles per liter (not moles to part of a liter)! So...we are adding .063 moles to .5 liters of solvent, but, molarity is always expressed in moles per liter, so we have to convert this: (.063 moles C5H5N/.5 liter) x 1 liter = .126 moles C5H5N So, if .063 moles of C5H5N dissolved in .5 liters gives a solution of the same concentration as 1.26 moles of C5H5N dissolved in 1 liter (note - we now have it in moles per liter!). As molarity is moles per liter...and adding 5 grams of pyridine (which is .063 moles) to .5 liters of solvent produces a solution of the same concentration (molarity) as dissolving 1.26 moles of solvent in 1 liter, we have produced a 1.26 molar solution.
The molarity of the solution can be calculated by dividing the moles of solute by the liters of solution. In this case, it would be 5 moles / 4.5 liters = 1.11 M.
The molarity of the solution is calculated using the formula: Molarity (M) = moles of solute / liters of solution. In this case, there are 0.75 moles of solute in 0.5 liters of solution (since 500 ml is equivalent to 0.5 L), so the molarity is 1.5 M.
The molarity of the solution is calculated by dividing the moles of solute (0.250 mol NaCl) by the liters of solution (2.25 L). Molarity = moles of solute / liters of solution Molarity = 0.250 mol / 2.25 L = 0.111 M
Molarity is calculated by dividing the moles of solute by the volume of solution in liters. The formula is Molarity (M) = moles of solute / volume of solution (in liters). It is important to have accurate measurements of both the moles of solute and the volume of the solution to determine the molarity.
The formula for molarity (M) is: moles of solute (in mol) / volume of solution (in liters). It can be written as: M = n/V, where n is the number of moles of solute and V is the volume of the solution in liters.
The molarity of the solution can be calculated by dividing the moles of solute by the liters of solution. In this case, it would be 5 moles / 4.5 liters = 1.11 M.
To find the molarity of a solution, divide the number of moles of solute by the volume of the solution in liters. Molarity (M) moles of solute / liters of solution.
To determine the molarity of a solution, you need to know the amount of solute (in moles) and the volume of the solution (in liters). Molarity is calculated by dividing the moles of solute by the volume of the solution in liters. The formula for molarity is M moles of solute / liters of solution.

To calculate the molarity of a solution, you need to know the volume of the solution in liters. Convert the volume from milliliters to liters and then calculate the molarity by dividing the moles of solute by the volume of the solution in liters.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution in liters. In this case, the molarity would be 0.15 M, which is calculated by dividing 0.45 moles by 3.0 liters.
The abbreviation for molarity is M. Molarity is calculated by dividing the moles of solute by the volume of solution in liters. The formula is M moles of solute / volume of solution (in liters).
