<PRE><B>Question 333604</B>
part a: -solve for V: D=m over V
D = {{{m/v}}}
Multiply both sides by v, results
Dv = m
Divide both sides by D, results
v = {{{m/D}}}
:
:
part b:- find the volume V of a sample if its density is 4.5 g/cm^3 and its mass is 36.0g.
v = {{{m/D}}}
Replace m and D with the given values:
v = {{{36/4.5}}}
v = 8 cu/cm is the volume
:
:
Check this mass: = the density * volume: 36 = 4.5 * 8 </PRE>
