A body of density 9.0g/cm³ appears to have a mass of 27.0g in a liquid of density 1.2g/cm³. what is the volume of the solid |

I bet when I was in SS3 this would have been a piece of cake; buh in 500 level, I simply have no idea.. And I feel good, as mind keeps telling me that "it ain't physics but chemistry, so yhu don't need to know it" |

Recall: Density = Mass/Vol Let V= Volume of solid Therefore mass of solid in air = density × vol = 9×V = 9V Mass of liquid displaced= mass in air - mass in Liquid = 9V- 27 But volume of Liquid displaced = Volume of solid Therefore, 1.2= 9V-27/V 1.2V= 9V-27 9V-1.2V=27 7.8V=27 V= 27/7.8 V= 3.5CM3 = Volume of solid 2 Likes |

SomeHenro:WOW, You are a genius I've been trying to help him solve the question for about an hour now, with two physics textbooks, two pen and a long note, still I couldn't solve it. Thanks bro |

SmithRussell:LOL, I was just staring at the question for several minutes, to the extent I had to get 2 physics textbooks, still I wasn't able to solve it ooo. Probably because it's been a long time since I studied the subject, 300L in a very unrelated course again. |
