<span>Just solve this by using the molar mass/molecular weight, and the avogadros number in a dimensional analysis
18.46 g Cu x (1 mole/64 g) x (6.022 x 10^23 atoms/1 mole) = 1.74 x 10^23 atoms
</span><span>67.69 g NaCl x (1 mole/58 g) x (6.022 x 10^23 formula units/ 1 mole) = 7.03 x 10^23 formula units
</span>44.99 g H2O x (1 mole/18 g) x (6.022 x 10^23 molecules/ 1 mole) = 1.51 x 10^24 molecules
<span>0.250 moles Mg x (24 g/1 mole) = 6 g
</span>48.096 g S x (1 mole/32 g) = 1.5 g
Atomic Mass.
Reactivity decreases as you go down a group.
Atomic Radius also decreases as you go down a group.
Valence electrons are the same within a group.
Atomic mass, however, increases as you go down a group.
Hope this helps!
