1 mole K ------------- 6.02x10²³ atoms
1.83 moles K ------ ?? atoms

1.83 x (6.02x10²³) / 1 =

1.101x10²⁴ atoms of K

hope this helps!

Chlorine gas reacts with aluminum metal producing aluminum chloride. What mass of chlorine reacts with 9.00g of Al to form AlCl3
Anit [1.1K]
The  mass of  chlorine   that react  with  9.00 g  of Al to form AlCl3  is   35.465  grams

     Explanation
write  the equation  for  reaction
that is
2 Al +  3 Cl2  = 2 Al CL3
find  the moles  of    Al  reacted

moles = mass/molar mass

  9 g/ 27  g/mol = 0.333  moles  of Al

by use  of mole ratio between   Al to  Cl2    which is  2:3   find the moles of  Cl2

mole  of cl2 =  0.333 x3/2 = 0.4995  moles


mass of  Cl2  is therefore =  moles  x  molar mass

= 0.4995  x71 =  35.465  moles

A gas that was cooled to 200 Kelvin has a volume of 65.8 L. If its initial volume was 132.4 L, what was its initial temperature?
Mandarinka [93]

Answer:

Initial temperature, T1 = 99.4 Kelvin

Explanation:

<u>Given the following data;</u>

  • Initial volume, V1 = 65.8 Litres
  • Final temperature, T2 = 200 Kelvin
  • Final volume, V2 = 132.4 Litres

To find the initial temperature (T1), we would use Charles' law;

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles' law is given by the formula;

\frac {V}{T} = K

\frac {V_{1}}{T_{1}} = \frac {V_{2}}{T_{2}}

Making T1 as the subject formula, we have;

T_{1} = \frac {V_{1}T_{2}}{V_{2}}

Substituting the values into the formula, we have;

T_{1} = \frac {65.8 * 200}{132.4}

T_{1} = \frac {13160}{132.4}

<em>Initial temperature, T1 = 99.4 Kelvin</em>
