What is the weight of one mole?
The number of atoms or other particles in a mole is the same for all substances. The mole is related to the mass of an element in the following way: one mole of carbon-12 atoms has 6.02214076 × 1023 atoms and a mass of 12 grams.
What is the weight of NaCl?
58.44 g/molSodium chloride / Molar mass
How many moles of NaCl are in 3g of NaCl?
1 Answer. David G. 3 g is 0.075 mol of NaCl . Multiply this by Avogadro’s number to find that this amount of salt contains 4.5×1022 formula units of NaCl .
How do you find the molecular weight of NaOH?
– The atomic weight of the sodium is 23, the atomic weight of the hydrogen is 1, and the atomic weight of the oxygen is 16. – Now we can calculate the molar mass or molecular weight of the sodium hydroxide by using the formula below. Molecular weight of the NaOH= 23 + 1 + (16) = 40.
How do you find molecular weight from molarity?
Divide the value of moles you just calculated by the total volume of the solution. This volume must be in units of liters. The result of this calculation is the molarity of the solution, M, in units of moles chemical per liter solution.
How do you calculate moles of NaCl?
The formula for the number of moles formula is expressed as.
How is the formula mass of NaCl determined?
Example and Calculation. The molecular formula for glucose is C 6 H 12 O 6,so the empirical formula is CH 2 O.
What is the relative formula mass of NaCl?
Whenever you see the words ‘relative’ in chemistry, it means the mass number. Example. Therefore, the relative formula mass of H2O is 18. 23 + 35.5 = 58.5. So the relative formula mass of NaCl is 58.5. As explained earlier, for most elements the relative atomic mass is equal to their mass number.
How do you calculate Gram molecular weight of NaCl?
