Near Tatooine's famous Mos Eisley Space port you found a 781.19 mL block of gold. What is the mass in kilograms of this block? (1000 g = 1 kg, 2.2 lbs = 1 kg)

Metal Density (g/cm3)
Aluminum 2.7
Zinc 7.1
Copper 9.0
Silver 10.5
Lead 11.4
Gold 19.3

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

i think is conclusions.i think so
