It would be B because you want to know which TEMPERATURE is the best for the plant. Different brightness for a bulb will give different amounts of heat. Since the amount of heat is your INDEPENDENT VARIABLE, you have to change the amount of heat for each plant, so the brightness of bulbs. Therefore, B is your answer!

How many moles are in 1.20 times 10^25 atoms of phosphorus
Stels [109]

19.927 moles are in 1.20 times 10^{25} atoms of phosphorus.

<h3>What are moles?</h3>

A mole is defined as 6.02214076 ×10^{23} of some chemical unit, be it atoms, molecules, ions, or others.

1 mole of any substance contain Avogadro's number of molecules so we can calculate the number of moles by dividing the provided number of atoms over Avogadro's number to obtain the number of moles .

Moles= \frac{Atoms}{\;Avogadro's \;number }

Moles=  1.20 X 10^{25} atoms ÷ 6.022 X 10^{23}

= 19.927

Hence, 19.927 moles are in 1.20 times 10^{25} atoms of phosphorus.
