What is the mass (in kg) of 6.89 × 1025 molecules of co2? the molar mass of co2 is 44.01 g/mol.

Answer : The mass of is, 5.034 Kg

Explanation :

First we have to calculate the moles of .

As, molecules of present in 1 mole of

So, molecules of present in mole of

Now we have to calculate the mass of .

Therefore, the mass of is, 5.034 Kg

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
