How many mols are present in the a sample of silver nitrate which has<br> 5.3x10^24 molecules.
Westkost [7]

Answer:  5.3 x 10^24 formula units of silver nitrate is equivalent to 8.8 moles of silver nitrate. Silver nitrate is an ionic compound, therefore, its representative particle is called a "formula unit" instead of molecule. For every mole of a substance, we know that there are 6.022 x 10^23 representative units of that substance. The amount of particles in one mole of substance is called Avogadro's number.

Further Explanation:

We can convert from number of representative particles to moles using the formula:

\boxed {no. \ of \ moles \ = \ ( given \ no. \ of \ particles) \ (\frac{1 \ mole}{\ 6.022 \ x 10^{23} particles})}

For this problem, we can calculate the number of moles by plugging in the given values to the equation above,

no. \ of \ moles \ = (5.3 \ x \ 10^{24} \ formula \ units \ AgNO_{3}) \ (\frac{1 \ mole \ AgNO_{3}}{6.022 \ x 10^{23} \ formula \ units AgNO_{3}}) \\\\\boxed {no. \ of moles \ AgNO_{3} \ = \ 8.8 \ moles}

Which factors are most likely to limit population growth in cloud forests?
antoniya [11.8K]

Answer:

Option (4)

Explanation:

The cloud forests are located at high elevated areas in the tropical and subtropical regions. They are characterized by the presence of clouds that maintains a relatively cold environment, favoring the existence of various type of plant and animal species. The temperature is comparatively low, rich in moisture content and the amount of sunlight also is low in this region. The change in these factors can cause a decrease in the population growth in these cloud forests.

Thus, low moisture content in the atmosphere and excessive amount of sunlight in this type of forest can lead to the reduction in its population.

Hence, the correct answer is option (4).
