-First we have to work out what’s in parenthesis.
(8*10^-3)=(8*0.001)=0.008
-This is for the second parenthesis
(2*10^-4)=(2*0.0001)=0.0002
-Now we multiply them together
ANSWER: 0.0000016
D = m / V
<span>m = 1.26 g </span>
<span>V = s^3 = 4.1^3 = 68.921 cm^3 </span>
<span>so </span>
<span>D = 12.6 / 68.921 = 0.1828 g/cm^3 </span>
<span>and this corresponds to choice (a)
</span>
