check my calculation please?
« on: February 06, 2011, 06:28:49 PM »
1)A 93.612 g metal sample is placed in a 50 ml graduated cylinder containing 23.2 ML of water and the water level rises to 33.7 mL.  Calculate the density of the metal sample.

Density= mass/volume
Mass =93.612
Volume= 33.7 ml – 23.2 ML
Density= 93.612 g/10.5ml= 8.92g/ml
Density equals 8.92g/ml

2) Calculate lead the volume of 135 g block of aluminum.  The density of aluminum is 2.70 g/cm^3

Volume = mass /  density, so v =135 g/2.70g/cm3 – volume=502.9cm^3

Hello again. 1 is correct. For 2, check your math. Ironically, 1 is the harder one.
