How many meters equal to 250 centimeters?
250 centimeters is 2.5 meters.
How many gold atoms are there in a sphere that is 13 in diameter?
I will use the volume of a sphere formula and the density of gold to find this answer. The radius of gold is 144 picometers. 13 inches (2.54 centimeters/1 in)(1 meter/100 centimeters)(1012 picometers/1 meter) = 3.30 X 1011 picometers --------------------------------/2 = 1.65 X 1011 picometers in radius of this sphere =================================So, that means that the radius of the gold would be as to the sphere..., 1.65 X 1011 picometers/144 picometers = 1.15 X 109 picometers of gold radius here =======================================================( final answer )
How many centimeters are in 250 meters?
25,000
The diameter of an aluminum atom is 250 picometers How many aluminum atoms must be placed end to end to make a chain of aluminum atoms one foot long?
There are 30.48 centimeters in a foot. Converting picometers to centimeters, each aluminum atom is 2.5 x 10^-8 cm. Thus, 30.48 cm / 2.5 x 10^-8 cm gives approximately 1.22 x 10^9 aluminum atoms needed to make a chain of aluminum atoms one foot long.
