Page 7 of 10 8A55.3 Density rcar bec mmber of practical ues. It is the relatioesbup betwen mass and vobume, and therefore can be approached in ether of two POSTLAB QUESTIONS Density has a ol be used to calculate mass or volume if one of the two and the density are known. Such problems density-mass or d-m Aother wanbstituate the values you have inko the equation, and soe for the value you do not have Since you can Because the um achig density problems is to use the factor label, or unit conversion method. volume its of desity are giml, density can be used as conversion factor to convert from g to 8. Here are some problems to metal tin can exist in dillerent forms. Gray tin has a density of 5.75 g/ml What would be the volume of a piece of gray tin with a mass of 15.0g? 1. The b. W Vhat would be the mass of a pice of gray tin with a volume of 230. ml? c What would be the mass of a rectangular box made out of gray tin if the linear dimensions of dhe box are: 15.56 cm long, 10.20 cm wide, and 5.64 cm high. Hint: refer to Measurement Lab. Densitygiml 2. At the right is a list of sivery metals and their densities. tal A piece of unknown metal is found to have a volume ofmagnesium 1.74gml. aluminum 2.70 g/mL 37.8 mL and a mass of 270. g. Which of these metals is the unknown likely to be? 45 g/mL antimony zinc iron lead 6.68gmL 7.14 gml 7.87 gmL. 11.3 g/mL

4. Suppose that a student performed the experiment and calculations perfectly as directed except that, unknown to the student, the balance was not zeroed but weighed 0.100 g too high throughout the experiment. Would the calculated val- ue for the density of the unknown liquid be correct? That is, would it be equal to, higher than, or lower than the true value.
