Answer:
The volume for a piece of gold that has the mass of 318,67 g is 16,50cm3
Explanation:
Density = mass / volume
Volume = mass/ density
Volume = 318,97 g / 19,32 g/cm3 = 16,50cm3
Δ 1.36 (3H, d, J = 5.5 Hz)
<span>CH*3-CH(X)(Y) </span>
<span>δ 4.63 (1H, q, J = 5.5 Hz) </span>
<span>CH3-CH*(X)(Y) </span>
<span>Note: X anY can't have hydrogen attached, so they are probably O. </span>
<span>δ 3.32 (6H, s); δ 4.63 (1H, q, J = 5.5 Hz) </span>
<span>There is only C2H6O2 remaining, so this must be two CH3 groups; the attachment must be as an ether, and there must be two of them: </span>
<span>CH3-CH(OCH*3)2</span>
