I believe the question is
Block of brass made of copper at density 9g/cm3 and zinc 100 cm3 with density of 8.5g/cm3
The question don't contain sufficient data to calculate.
Brass may have zinc content varies between 5 - 15% this ratio meant to be fix to calculate out ratio copper use.
Let presume fix zinc content to 10% that is 90% copper use
Zinc additive is 100 x 8.5 = 850 gram
Copper additive is then 850x90/10 = 76,500 gram = copper volume of 76,500/9 = 850 cm3
Net weight of this block is then 850+76,500 = 77,350 gram
No, copper and brass doesnot have same density.
Copper is cheaper than brass.
The percentages of copper and zinc in the alloy.
Depends on what the usage is do you want YELLOW Brass 60% Copper 40% Zinc Or do you want RED BRASS? 85% Copper 15% Zinc
Brass is a mixture
No, copper and brass doesnot have same density.
density of copper = 8930 kg/m^3 & density of brass = 8700 kg/m^3 copper is heavier
The SI Unit of density is kg/m3 it is calculated by mass / volume The density of steel usually ranges between 7750 and 8050 kg/m3 The density of brass is usually between 8400 and 8730 kg/m3 The density of copper is 8940 kg/m3 at room temperature The density of aluminum is 2700 kg/m3 at room temperature So the most dense is copper, followed by brass, followed by steel, followed by aluminum
no!!! Brass is an alloy of copper and tin; frequently other alloying elements are contained.
Since brass is made by combining differing amounts of copper and zinc, there is no uniform density per cubic inch. Therefore, you will have to conduct experiments to deduce this amount for yourself.
Copper is cheaper than brass.
Brass is the alloy of copper and zinc.
Both brass and copper are conductors.
Brass is an alloy of copper and zinc.
Brass is a metal alloy of mostly copper & zinc.Bronze is an alloy of mostly copper & tin.Bronze is often redder, stronger, more resistant to corrosion, harder and the making of bronze is much older than brass.
The percentages of copper and zinc in the alloy.
Depends on what the usage is do you want YELLOW Brass 60% Copper 40% Zinc Or do you want RED BRASS? 85% Copper 15% Zinc
