Which one has the greatest mass?
1. 3.55 mol o atoms
2. 4.52 g o atoms
3. 0.0032 kg o2 molec
4. 7.39 × 1023 o2 molec

The correct answer is Option 1.

Explanation:

For the given options:

To calculate the number of moles, we use the equation:

Moles of Oxygen = 3.55 mol

Molar mass of Oxygen = 16 g/mol

Putting values in above equation, we get:

Mass of oxygen atoms = 56.8 g

Mass of oxygen atoms = 4.52 g

Converting this into grams, we use the conversion factor:

1 kg = 1000 g

So, 0.0032 kg = 3.2 g

Mass of molecule = 3.2 g

According to mole concept:

1 mole of an atom contains number of atoms.

If, number of atoms occupies 32 grams of oxygen molecule.

So, number of atoms will occupy =

Mass of molecule = 39.2 g

Hence, the greatest mass is coming out from option 1.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
