To solve this you need to know the relationship that density = mass divided by volume
We're given a length of a side of a cube as 2.5cm so to find the volume of the cube we need to cube it (length x bredth x height)
volume = (2.5)3 = 15.625cm3
so if density = mass(136.95g)/volume(15.625cm3)
density = 8.7648 g cm-3
in textbooks its given as (8.3- 8.7 gcm-3) as a typical density of brass.
8.4 grams per cubic centimeter
Brass is any alloy of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties.The density of brass is 8400 kilograms per cubic meter or 8.3 grams per cubic centimeter.
No, copper and brass doesnot have same density.
The density of brass can vary from 8300 to 8700 kg/m3.
Brass is a name of alloy composed of two elements: copper and zinc. Each of those has different density and since their ratio in brass may vary, also the brass density may be different.
First, two things. 1) Since brass is a solid at standard temperature and pressure, it is unusual to specify its density in fluid volume units, such as gallons. 2) Brass is an alloy comprising differing amounts of different metals, so its density must be specified as a range. Brass is about 8.5 times denser than water. It has a density of 8.4 to 8.75 grams per cubic centimeter. That translates to 70 to 73 pounds per US gallon.
Brass refers to several different alloys whose relative density ranges from 8.4 to 8.73
You can use 8.5 as Brass density and work out the weight
density of copper = 8930 kg/m^3 & density of brass = 8700 kg/m^3 copper is heavier
