Substance a Has a Density of 3 G/cm³ and Substance $\frac { V _ { \mathrm { A } } } { V _ { \mathrm { B } } }$

Multiple Choice

Substance A has a density of 3 g/cm³ and substance B has a density of 4 g/cm³. In order to obtain equal masses of these two substances, what must be the ratio of the volume of A to the volume of B?

A) $\frac { V _ { \mathrm { A } } } { V _ { \mathrm { B } } }$ = $\frac { 1 } { 3 }$

B) $\frac { V _ { \mathrm { A } } } { V _ { \mathrm { B } } }$ = $\frac { 4 } { 3 }$

C) $\frac { V _ { \mathrm { A } } } { V _ { \mathrm { B } } }$ = $\frac { 3 } { 4 }$

D) $\frac { V _ { \mathrm { A } } } { V _ { \mathrm { B } } }$ = $\sqrt { \frac { 3 } { 4 } }$

E) $\frac { V _ { \mathrm { A } } } { V _ { \mathrm { B } } }$ = $\frac { 3 } { 1 }$
