What is the total worth of this quantity of gold?

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

Bulk platinum cost about $1158 dollars per ounce (28.35 g = 1 ounce) how much is this per gram?

The Great Star of Africa weighs 530.40 carats. The Great Star of Africa also has an estimated value of $2 billion. What is the price per carat for the Great Star of Africa?

In 1999, scientists discovered a new class of black holes with masses 100 to 10,000 times the mass of our sun, but occupying less space than our moon. Suppose that one of these black holes has a mass of 8×103 suns and a radius equal to one-half the radius of our moon. What is its density in grams per cubic centimeter? The mass of the sun is 2.0×1030kg and the radius of the moon is 2.16×103mi. (Volume of a sphere =43πr3.)

In 1999, scientists discovered a new class of black holes with masses 100 to 10,000 times the mass of our sun, but occupying less space than our moon. Suppose that one of these black holes has a mass of 1×10^3 suns and a radius equal to one-half the radius of our moon. What is its density in grams per cubic centimeter? The mass of the sun is 2.0×10^30 kg and the radius of the moon is 2.16×10^3 mi (Volume of a sphere =4/3πr^3)

A thief plans to steal a gold sphere with a radius of 28.4 cm from a museum. If the gold has a density of 19.3 g/cm^3, what is the mass of the sphere in pounds? [The volume of a sphere is V=(4/3)πr^3]. Express your answer in pounds to 3 significant figures.

A student gently drops an object weighing 16.9 g into an open vessel that is full of ethanol, so that a volume of ethanol spills out equal to the volume of the object. The experimenter now finds that the vessel and its contents weigh 10.6 g more than the vessel full of ethanol only. The density of ethanol is 0.789 g/cm. What is the density of the object? Density = g/cm³
