question 37

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