30 points calculate the number of moles of each element (number of moles of na & number of moles of cl) in nacl in the sample. (use your answer from part a as your starting point.) show your work. known: -17.44g (nacl sample) -molar mass = 58.44 (both) 17.44g nacl * 1 mol nacl/58.44g nacl = 0.298 (mol of nacl)

It contains 0.298 mole of Na and 0.298 mole of Cl.

Explanation:

To get the number of moles of each element in NaCl we should know that every mole of NaCl contains 1.0 mole of Na and 1.0 mole of Cl:

NaCl → Na + Cl

It is clear that each mole of NaCl contains one mole of Na and one mole of Cl.Using cross multiplication:

1.0 mol NaCl → 1.0 mol Na

0.298 mol NaCl → ??? mol Na

The number of moles of Na atoms in NaCl = (1.0 mol Na x 0.298 mol NaCl) / (1.0 mol NaCl) = 0.298 mol of Na atoms.By the same way; the number of moles of Cl atoms = (1.0 mol Cl x 0.298 mol NaCl) / (1.0 mol NaCl) = 0.298 mol of Cl atoms.

Most smaller stars don't have a radiative zone.
