A sample of Mo(NO3)6 has 2.22 x 10^22 nitrogen atom, how many oxygen atoms does the sample have?
goldfiish [28.3K]

There are 3.98 × 10^23 atoms of oxygen in the sample.

Given that;

1 mole of Mo(NO3)6 contains 6.02 × 10^23 atoms of Nitrogen

x moles of Mo(NO3)6 contains 2.22 x 10^22 atoms of nitrogen

x = 1 mole × 2.22 x 10^22 atoms/6.02 × 10^23 atoms

x = 0.0368 moles

The number of oxygen atoms in the sample is given by; 0.0368 × 6.02 × 10^23 × 18

Therefore, there are 3.98 × 10^23 atoms of oxygen in the sample.

Horticulturists know that, for many plants, dark green leaves are associated with low light levels and pale green with high leve
nikitadnepr [17]
  • In the reduction process of photosynthesis, electrons are transported from water to carbon dioxide.
  • According to photon theory here the photons behave as light energy particle.
  • By capturing sun energy (photons), chlorophyll aids in this process.An electron in the chlorophyll molecule gets excited from a lower to a higher energy state when chlorophyll receives energy from sunlight.
  • Excessive sunshine is the main cause of leaves turning a darker green color. Lack of sunlight causes a plant's leaves to create more chlorophyll, which is what gives the plant its green hue.
  • The color of the leaf is darker green than typical because of the increase in chlorophyll concentration per unit area.
<h3>What is photon theory?</h3>

The photon theory of light states that photons have simultaneous particle and wave behavior. pass through empty space at a constant speed, or "the speed of light". possess rest energy and zero mass.
