2 MOLES OF POTASSIUM BICARBONATE IS DECOMPOSED TO GIVE I MOLE OF CARBON DIOXIDE GAS AND 1 MOLE OF WATER VAPOUR. AT 120 DEGREES CENTIGRADE.
MOL WT OF POTASSIUM BICARBONATE IS 98
THEN 34 GRAMS BECOMES 0.346 M
0.346 M OF POTASSIUM BICARBONATE YIELDS 0.173 M OF CARBON DIOXIDE GAS AND 0.173 M OF WATER VAPOUR.
SIMILARLY, AT 5200 C TEMPERATURE AND AT 1.16 atm PRESSURE, THE YIELDS ARE 0.311 M OF CARBON DIOXIDE GAS AND 0.311 M OF WATER VAPOUR.
WHEN CONVERTED, IT COMES TO 0.070 L OF CO2 AND 0.030 L OF H2 O
