Question

convert given moles of substance into no. of molecules 0.5 moles of NaOH by using formula no. of molecules multiple arogodre's
​

Answer 1

Answer:

To convert moles to molecules, what you need to know are the weight of a sample, the sum of its atomic masses from the periodic table and a constant known as Avogadro’s number. In addition to the following steps, a moles to molecules calculator may be found online.

Step-by-step explanation:

Step 1: Find the Molar Mass of the Molecule

Find a periodic table of elements to find the molar mass of your sample. If the sample is made of one element, like calcium, locate the atomic mass on the periodic table. Atomic mass is usually listed below the symbol for that element.

If the sample is a molecule, like H2O, sum the molar masses of all the components. There are two hydrogen atoms and one oxygen atom; 2 (1.01 amu) + (16.00 amu) = 18.02 amu. This formula mass is numerically equal to the molar mass in grams/mole, and this means the molar mass of H2O is 18.02 grams/mole.Whether an individual element like calcium is used or a molecule like H2O, the procedure for finding the amount of atoms or molecules remains the same. Additionally, the relationship of moles to number of molecules is not dependent on the complexity of the molecule.
