one bottle of aspirin holds 250 tablets, each containing 150 mg of aspirin and sells for $2.95. Another bottle holds 125 tablets
AlladinOne [14]
I bottle:

250 * 150mg = 37500mg

If 37500mg ------- cost ------- <span> $2.95
so 1mg       ------- cost ------- x

x = 1mg*</span> $2.95 / 37500mg =  $7,87*10⁻⁵ 

II bottle

125 * 200mg = 25000mg

If 25000mg ---------- cost ---------- <span>$3.50
so 1mg       ---------- cost ---------- x

x = 1mg* </span>$3.50 / 25000mg = $0,00014=$1,4*10⁻⁴


$7,87*10⁻⁵  < $1,4*10<span>⁻⁴
</span>
1st bottle is better bargain cause 1mg of aspirin its cheaper than in 2nd.

Give explanations for the large drops in melting point from C to Si and from Ge to Sn.
____ [38]

As we move down the group, the metallic bond becomes more stable and the formation of forming covalent bond decreases down the group due to the large size of elements.

Covalent and metallic bonding leads to higher melting points. Due to a decrease in attractive forces from carbon to lead there is a drop in melting point.

Carbon forms large covalent molecules than silicon and hence has a higher melting point than silicon.

Similarly, Ge also forms a large number of covalent bonds and has a smaller size as compared to that of Sn. Hence melting point decreases from Ge to Sn.

The order will be C>Si>Ge>Pb>Sn.
