the radius of a gold atom is 1.35 angstroms. how many gold atoms would it take to line up a span of 8.5 mm?
serg [7]
The angstrom<span>, also known as the </span>angstrom<span> unit, is a measure of displacement equal to 0.0000000001 meter (10 -10 m). It would be helpful to convert the units of angstrom to mm. We do as follows:

diameter = 2 x 1.35 x10^ -10 m ( 1000 mm / 1 m ) = 2.7 x 10^-10 mm / atom

Number of gold atoms = 8.5 mm / </span>2.7 x 10^-10 mm / atom = 31481481481.481 atoms

How many terms are in a b c and d
ddd [48]
Um b is maybe 9n + 5 = 15n
um c is maybe 3 - 5 to the third power =3 - 125 = -122 + 7 = -115
maybe you have to add the positive 15n to -115 = -100n
um d is maybe 3b + 2c - 10c = 3b + -8c = -5 <span />

Step-by-step explanation:

A:

The question is asked when there is a "what" or a problem statement

B:

The only value or digits given is 54000

C:

in the Metric Scale Kilograms is 1000 times larger in value than grams thus 1000

D:

E:

Um.... just multiply 1000 ._. (That's the only way I can check it)

Hope this helps!
