How many molecules are in a gram of NaCl?
So, first we convert to moles: the molecular weight of salt is 58.44 grams per mole, so there are 1.71 x 10-6 moles per grain. If we multiply this by Avogadro's number, we get 1.03 x 1018 molecules of NaCl per grain of table salt.

How many grams are in sodium?
If you refer to your periodic table, the molar mass of Na (sodium) is 23.0 g/mol.
How many grams of NaCl are in 8 moles?
1 Answer. The mass of eight moles of sodium chloride is ≈500g .
How many molecules are there in NaCl?
A single unit of NaCl has a mass of 58.45 u; NaCl has a molar mass of 58.45 g. In each of these moles of substances, there are 6.022 × 1023 units: 6.022 × 1023 atoms of H, 6.022 × 1023 molecules of H2 and H2O, 6.022 × 1023 units of NaCl ions.
How many atoms are there in NaCl?
1 Answer. There are 2 atoms in NaCl. This is because there is 1 atom of Na (sodium) and 1 atom of Cl (chlorine) in each NaCl molecule.
How many moles are in NaCl?
So, the molar mass of NaCl = 35.5 gmol−1 +23 gmol−1= 58.5 gmol−1. Now, we have to use the following formula to calculate the number of moles of NaCl. The mass of NaCl is given as 20g. So, the number of moles of NaCl present in 20 g of NaCl is 0.342 mol.

How many grams are in a mole?
There are three steps to converting grams of a substance to moles: ▪ Step 1: Determine how many grams of a substance are in the problem. Use the periodic table to check the atomic mass, this is the number of grams per mole → 1 mole of Aluminum is 26.982 g ▪ Written as a fraction this is …

How do you find the gram formula mass of NaCl?
The formula of Sodium chloride is NaCl. The atomic mass of sodium is 22.99g/mol, and the atomic mass of chlorine is 35.45gmol. Thus, the formula mass of Sodium chloride is 22.99 + 35.45 = 58.44gmol.
How many moles are in 15 grams of NaCl?
1 Expert Answer From 15 g of Na you got 0.65246 mol. If you use this balanced equation, you can figure out what this means for moles of NaCl and therefore how many grams of NaCl.
How many grams are in a molecule?
This means that you can always find how many grams there are in a mol of any substance by finding the molar mass. For example, the molar mass of water (H2O) is 18.02 grams per mol. This means there are 18.02 grams of water in one mol of water.
How many moles are in a gram?
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.
How do you find the gram equivalent weight of NaCl?
Divide the molecular weight by the valence to calculate the equivalent weight. The equivalent weight of NaCl is 58.5/1 or 58.5.
How many atoms are NaCl?
1 Answer. There are 2 atoms in NaCl. This is because there is 1 atom of Na (sodium) and 1 atom of Cl (chlorine) in each NaCl molecule. Elements by themselves do not have a "number of atoms"- if you're talking about the atomic number, it's the number of protons (or electrons in a neutral atom) of an element.
