How many moles of chlorine are in 6.67x10^40 chlorine molecules?

Chemistry
2 answers:
Vladimir [108]3 years ago
6 0

To determine the moles of chlorine atoms you would first need to multiply your number by 2 and then divide that by 6.022 x 10^23 (Avogadro’s number). If you want to determine the number of moles of chlorine (Cl2), then you would divide that result by 2. So:

1.1076 x 10^17 moles of chlorine (Cl2)

2.2152 x 10^17 moles of chlorine (Cl) atoms.

To solve for the number of moles, we simply have to use the Avogadros number which states that there are 6.022 x 10^23 molecules per mole. Therefore:
 
number of moles = 6.67 X 10^40 chlorine molecules / (6.022 x 10^23 molecules / mole)
number of moles = 1.108 x 10^17 moles

Water has a boiling point of 100.0°C and a Kb of 0.512°C/m. What is the boiling
Neko [114]

Answer:

104.352°C

Explanation:

Data Given:

Boiling point of water = 100.0°C

Kb (boiling point constant = 0.512°C/m

Concentration of the Mg₃(PO₄)₂ = 8.5 m

Solution:

Formula Used to find out boiling point

               ΔTb = m.Kb . . . . . . (1)

where

               ΔTb = boiling point of solution - boiling point of water

So,

we can write equation 1 as under

               ΔTb = Tb (Solution) -Tb (water)

As we have to find out boiling point so rearrange the above equation

              Tb (Solution)  = m.Kb + Tb (water) . . . . . . . (2)

Put values in Equation 2

            Tb (Solution)  = (8.5 m x 0.512°C/m ) + 100.0°C

            Tb (Solution)  = 4.352 + 100.0°C

            Tb (Solution)  = 104.352°C

so the boiling point of Mg₃(PO₄)₂  8.5 m solution =  104.352°C
