Answer:
Orbital motion occurs whenever an object is moving forward and at the same time is pulled by gravity toward another object. ... The result is a circular or oval path called an orbit, in which one object keeps moving around the other. Because of the relatively great gravity of the sun, Earth orbits the sun

Answer:
There are 14.2 moles of carbon in 170.3 grams of carbon
Explanation:
The mass of one mole of carbon is known as the molar mass of carbon. the unit of molar mass is grams/mole, g/mol.
The molar mass of carbon is 12 grams. This means that for every 12 grams of carbon, one has one mole of carbon.
To determine the number of moles of carbon present in 170.3 grams of carbon, the given mass of carbon, that is 170.3 grams is divided by 12.
The formula to use is: number of moles = mass of substance/molar mass of substance
Number of moles of carbon = 170.3 g / 12 g/mol = 14.2 moles
Therefore, there are 14.2 moles of carbon in 170.3 grams of carbon
