The average mass of a chloroform molecule, CHCl3, is 119.37 amu, which is the sum of the average atomic masses of each of its constituent atoms.
The average mass of an aspirin molecule is 180.15 amu. The model shows the molecular structure of aspirin, C9H8O4.
Table salt, NaCl, contains an array of sodium and chloride ions combined in a 1:1 ratio. Its formula mass is 58.44 amu.
Each sample contains 6.022 × 1023 atoms —1.00 mol of atoms. From left to right (top row): 65.4 g zinc, 12.0 g carbon, 24.3 g magnesium, and 63.5 g copper.
Each sample contains 6.02 × 1023 molecules or formula units—1.00 mol of the compound or element. Clock-wise from the upper left: 130.2 g of C8H17OH (1-octanol, formula mass 130.2 amu), 454.4 g of HgI2 (mercury(II) iodide, formula mass 454.4 amu), 32.0 g of CH3OH (methanol, formula mass 32.0 amu) and 256.5 g of S8 (sulfur, formula mass 256.5 amu).
The number of molecules in a single droplet of water is roughly 100 billion times greater than the number of people on earth. (credit: "tanakawho"/Wikimedia commons)

To work this one out, it is necessary to divide the number of blue sweets by the ratio, to find the common denominator. 12 divided by 4 = 3. We can then multiply the consequent number by 3 to find the unknown quantity: 6 x 3 = 18. Therefore, if there are 12 blue sweets, there will be 18 pink ones (or 12:18) To find the total number of sweets, we need to add both sides of the scaled-up ratio 12 ...

HOW DO YOU CALCULATE MOLES OF WATER LOST IN A HYDRATE ...

2020-07-04

How many grams of water was lost from the hydrate? In our example, 16 grams / 160 grams per mole = 0.1 moles. Divide the mass of water lost when you heated the salt by the molar mass of water, roughly 18 grams per mole. In our example, we lost 9 grams of water; if we divide 9 by 18, we get 0.5 moles of water lost.

Calculate the molarity – Use the titration formula. If the titrant to analyte ratio is 1:1, use the equation: acid_molarity * acid_volume = molarity_of_base * volume_of_base. For ratios other than 1:1, you need to modify the formula. Example: 35 ml of 1.25 M HCl acid is needed to titrate a 25 ml solution of NaOH. In that case, you can use the ...

Step 2: Calculate the molar ratios. To calculate the molar ratios, you put the moles of one reactant over the moles of the other reactant. This gives you a molar ratio of #"Al"# to #"I"_2# of #0.04448/0.009456# Usually, you divide each number in the fraction by the smaller number of moles. This gives a ratio in which no number is less than 1.
