Calculate the density of copper in g/cm^3:
A cube of copper measures 4.5cm on a side and weighs 813 g.
4.5cm x 4.5cm x 4.5cm = 91.1cm^3
D= m/V
813g / 91.1cm^3 = 8.9g/cm^3
Where can a person go on campus to see examples of sustainable technology / appropriate tech? (Not just solar panels but the whole building)
CCAT
Which term is the "weakest link" in this expression:
4.73 x 81.9763 x 1.000 =
4.73
Express 50 degrees Celsius in Fahrenheit:
122 F
F= (9/5C) + 32
F= (9/5 x 50) + 32 = 122F
In which diagonal direction does atomic radius increase? (i.e. up + left)
down and to the right
Calculate the density of zinc in g/cm^3
A cube of zinc measures 5.5cm on a side and weighs 1186g
5.5cm x 5.5cm x 5.5cm = 166cm^3
D = m/V
1186g / 166cm^3 = 7.1g/cm^3
