1 mol = 6.022 x 10^23 molecules (This is Avogadro's number)so 4.0 x 10^21 molecules x (1 mol / 6.022 x 10^23 molecules) = 6.6 x 10^-3 moles... Show More

6.022 * 10^23 molecules = 1 mole1 molecule = 1 / (6.022 * 10^23) molethus 4.0 x 1021 molecules = (4.0 x 10^21) / (6.022 * 10^23)= 0.0066423 moles or 6.64 * 10^-3 moles... Show More

(a) PV = nRT they supply you T, P, and V. go look up R on your e book. do not neglect to covnert T to kelvins. resolve for n, the style of moles. (b) multiply your style for (a) by skill of Avocado's style (or Avogadro's I neglect--look it up in case you don't be conscious of it).... Show More
