Based on the stoichiometry of NaCl, for every one mole of NaCl there is one mole of Na+ and one mole of Cl-. Therefore, there are 1.5 moles Na+ and 1.5 moles Cl-, totaling 3 moles of ions altogether
Based on the stoichiometry of NaCl, for every one mole of NaCl there is one mole of Na+ and one mole of Cl-. Therefore, there are 2.5 moles Na+ and 2.5 moles Cl-, totaling 5 moles of ions altogether.
To find the number of moles in 234g of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is 58.44 g/mol (sodium = 22.99 g/mol, chlorine = 35.45 g/mol). So, 234g ÷ 58.44 g/mol = 4 moles of NaCl.
0.051 molesWe know the molecular weight of NaCl is 58.443 g/mol and that the formula for the dissociation of salt in water looks like this:NaCl (aq)-->Na+ + Cl-So we can see that there is a one to one mole ratio between NaCl and sodium ions. All we have to do to find the moles of ions is3.00g * 1mol NaCl/58.443 g NaCl = 0.051 mol NaClFrom here we apply the ratio of 1 mol NaCl : 1 mol Na+ (though, since the ratio is one, it's not really necessary in this case):0.051 mol NaCl * 1 mol Na+/1mol NaCl = 0.051 mol Na+
To convert moles to grams, you need to use the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 1.6 mol of NaCl would be equal to 1.6 mol * 58.44 g/mol = 93.504 grams of NaCl.
To determine the number of Na ions in 4.2 g of NaCl, we need to first calculate the amount of NaCl present. The molar mass of NaCl is 58.44 g/mol. This means that in 4.2 g of NaCl, there are 4.2/58.44 = 0.072 mol of NaCl. Since NaCl dissociates into 1 Na+ ion and 1 Cl- ion, there are 0.072 mol of Na+ ions in 4.2 g of NaCl. To find the number of Na+ ions, you would then multiply the number of moles by Avogadro's number (6.022 x 10^23).

To find the number of moles in 737g of NaCl, first calculate the molar mass of NaCl, which is 58.44 g/mol. Then divide the given mass (737g) by the molar mass to get the number of moles. Number of moles = 737g / 58.44 g/mol ≈ 12.61 moles of NaCl.
To find the number of moles in 234g of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is 58.44 g/mol (sodium = 22.99 g/mol, chlorine = 35.45 g/mol). So, 234g ÷ 58.44 g/mol = 4 moles of NaCl.
13(g) / 58.5(g/mol) = 0.22 mol NaCl
There will be 6.022 x 10^23 sodium ions in 2.00 mol of NaCl. This is because one mole of NaCl contains one mole of sodium ions, and Avogadro's number (6.022 x 10^23) represents the number of entities in one mole of a substance.

To convert moles to grams, you need to use the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 1.6 mol of NaCl would be equal to 1.6 mol * 58.44 g/mol = 93.504 grams of NaCl.
To determine the number of moles of NaCl, you need to know the mass of NaCl you have and the molar mass of NaCl (58.44 g/mol). You can then use the formula moles = mass / molar mass to calculate the number of moles of NaCl.
To determine the number of moles in 50g of NaCl, you first need to find the molar mass of NaCl, which is approximately 58.44 g/mol. Then, you divide the given mass by the molar mass to find the number of moles. So, 50g of NaCl represents approximately 0.855 moles (50g / 58.44 g/mol = 0.855 mol).
To determine the number of Na ions in 4.2 g of NaCl, we need to first calculate the amount of NaCl present. The molar mass of NaCl is 58.44 g/mol.

To convert moles to grams, use the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 6.5 moles of NaCl would be 6.5 moles x 58.44 g/mol = 379.26 grams of NaCl.
The mole fraction of NaCl in the solution is calculated by dividing the moles of NaCl by the total moles of NaCl and water. In this case, the mole fraction of 18 mol NaCl in a solution of 100 mol water is 0.15 (18 mol NaCl / (18 mol NaCl + 100 mol water)).
