17. How many moles are there in a sample containing 1000 molecules of H2O?18. If you wanted a sample of H2O containing 6 x 23mol

Viefleur [7K]

17) mol of $H_{2}O$ = $\frac{no. of molecule}{L}$
= $\frac{1000 molecules}{6.03 * 10^{23} molecules/mol }$
= 1.658 *    $10^{-21} mol$

18) mol = $\frac{molecule}{L}$
   $\frac{Mass}{Mr} = \frac{Molecule}{L}$
Let mass of oxygen = x
   $\frac{x}{(2 * 1) + (16)} = \frac{6 * 10^{23} }{6.03 * 10^{23} }$
$x = (6 * 10^{23} ) (18 g/ mol)$
= 17.9 g
