1 mol of any substance = 6.022 × 10^23 particles
Use the formula
Number of Na+ ions = moles of NaCl × 6.022 × 10^23
Given:
Moles of NaCl = 0.949
Calculate
Number of Na+ ions = 0.949 × 6.022 × 10^23
Number of Na+ ions = 5.715 × 10^23
Answer:
5.72 × 10^23 Na+ ions

Number of sodium ions = Number of chloride ions = 0.949 moles x 6.022 x 10²³ ions/mole
Number of sodium ions = 0.949 moles x 6.022 x 10²³ ions/mole 5.70 x 10²³ sodium ions
There are approximately 5.70 x 10²³ sodium ions in 0.949 moles of sodium chloride (NaCl).

mass of 1.00 mol sodium

Weegy: Sodium has an atomic mass of 22.99. Therefore 1 mole of it weighs 22.99 grams. Similarly a mole of bromine weighs 79.9 grams. [ A mole of sodium bromide - NaBr - contains 1 mole each of sodium and bromine (note that this is not true for all chemical salts) and so 1 mole of it weighs 102.89 grams. ] (More)

Solution:
The molar mass of sodium (Na) is approximately 22.99 grams per mole (g/mol).

Therefore, the mass of 1.00 mole of sodium is:

1.00 mol x 22.99 g/mol 22.99 grams

So, the mass of 1.00 mole of sodium is approximately 22.99 grams.

Solution:
Now, you can calculate the mass of 1.35 moles of iron (Fe):

Mass (grams) = Number of moles × Molar mass
Mass (grams) = 1.35 mol × 55.845 g/mol
Mass (grams) 75.35675 grams

So, the mass of 1.35 moles of iron (Fe) is approximately 75.36 grams.

Mass = Moles × Molar Mass
Molar mass of oxygen (O) = 16.00 g/mol
Moles = 24.5 mol
Mass = 24.5 × 16.00 = 392.00 grams
Answer: 392.00 grams of oxygen.
