The densest known form of matter is the metal Osmium, with a density of 22.48g/cm3. A grapefruit wiht a diameter of 10.50cm weighs 0.750lbs. How many pounds does a sphere of Osmium weigh?   NOTE: 453.6g = 1lb; density=mass/volume and V = (4/3)πr3 and d=r/2.

one box of iron nails contains 85 nails and weighs 0.260lbs lbs total. The density of iron is 7.86g/cm^3 . if 35 nails are added to a graduated cylinder containing 17.65mL of water what is the new level of water in mL in the cylinder.

At 25.0 ºC the density of dichloromethane is 1.325 x 103 kg / m3. If 10.0g of dichloromethane at 25.0ºC can completely fill a container, what is the maximum mass of water, in grams, that can be added to the same container at 25.0°C?

The density of liquid mercury is 13.5 g/cm3. What mass (in kg) of mercury is required to fill a 2.00L container?

Density = Mass /volume                63.7410g/                                                                   6.336 cm^3 is this right ?

You just measured a metal cylinder and obtained the following information: mass = 3.543 g diameter = 0.53 cm height = 4.4 cm Determine the volume (V) and density of the cylinder. (V=nr2 h, where r = radius, h = height, π = 3.14) S A Volume of the cylinder = 0.87 cm3; density of the cylinder = 3.7 g/cm3 B Volume of the cylinder = 0.97 cm3; density of the cylinder = 2.7 g/cm3 C None of the above have both the volume and density correctly reported E Volume of the cylinder = 0.97 cm3; density of the cylinder = 3.7 g/cm3 Volume of the cylinder = 0.87 cm3; density of the cylinder = 2.7 g/cm3

The density of gold is 19.3 g/cm^3.  What is the density of gold in lb/in^3? (1lb = 454 g , 1 in = 2.54 cm)

The density of water is 1.00 g/cm3. Express this density in lb/m3.  (1 oz = 28.34 g)

The density of liquid mercury is 13.5 g/cm3. What mass (in kg) of mercury is required to fill a 2.00 L container?
