Question

A student following the procedure described in this module collected the following data:
Mass Mg,g is 0.243
Initial syringe volume, mL is 1.0
Final syringe volume, mL is 26.5
Barometric pressure, torr is 754
Temperature, K 298


What would be the effect on the result of mistakenly adding 2.43 times 10^-3 g Mg to 4.0 mL of 0.1M HCl, rather than to 4.0 mL of 1.0M HCl as instructed?




If the temperature and pressure remain constant how does the volume of a gas sample vary with the number of moles of gas present?

Explanation / Answer

exothermic reaction
