Question
In the preparation of 60 mL Magnesium citrate in the laboratory, you are required to:calculate for the volume of Carbon dioxide released from the hydrated double salt of Magnesium carbonate when reacted with Citric acid if 2.57 g of Magnesium carbonate is used.
MW of Magnesium carbonate = 485.65 g/mol H3C6H5O7 = 192.12 g/mol
Equations:
(MgCO3)4 .Mg(OH)2 .5H2O + 5H3C6H5O7 → 5MgHC6H5O7 + 4CO2 + 11H2O
3KHCO3 + H3C6H5O7 → K3C6H5O7 + 3CO2 + 3H2O
Reacting ratio: 1mol (MgCO3)4 .Mg(OH)2 .5H2O = 4 mol CO2
1 mol of any gas at STP occupies a volume of 22.4 L or 22, 400 mL
Choices:
| a |
385.71 mL |
|
| b |
496.23 mL |
|
| c |
365.20 mL |
|
| d |
474.15 mL |
