1.) What is the mass of the metal chromium (density 7.18g/cm3) ocupies the same volume as 100.0g of aluminium(density 2.70g/cm3).2.) Calculate the volumea.) in cubic meters(m3) for an automobile luggage compartment with dimensions of 36 in * 40 in * 56in.b.) in cubic cm (cm3) for a copper bar that is 26 in long, 2.0 in high, and 2.0 in wide.
1.) We first need to find the volume of the aluminum.dm/v --- v m/d. volume of aluminum 100.0-g / 2.70 g/cm^3 --- v 37.0 cm^3. Now, a piece of chromium having the same volume would have a mass of: m d x v --- 7.18-g.cm^3 x 37.0 cm^3 266-g 2a.) convert the measurement, currently in inches into cm first, then into meters: 1 inch 2.54 cm and 100 cm 1 meter 36 in x (2.54 cm / 1 in) x (1 meter / 100 cm) .914 m. 40 in x .0254 m/in 1.02 m, 56 in x .0254 m/in 1.42 m V 0.914-m x 1.02-m x 1.42 m 1.33 m^3 2b.) convert inches to cm: 26 in x 2.54 cm/in 66.04------- 2.0 in x 2.54 cm/in 5.08 cm------ V 66.04-cm x 5.08-cm x 5.08 cm 1.70 x 10^3 cm^3
Whoever told you that is full of it.Bikes have had fuel injection and radial tires for years.Not all of them of course,but lots of them do.
