The Ideal gas law: pV=nRT
n=const.
R=const.
V~T, it means If temperature increase than volume of gas increase.
if temperature decrease than volume of gas decrease.
The ratio of moles of AI(NO3)3 to moles Na2CO3 in the reaction is 2:3
In the reaction 2 moles of AI(NO3)3 reacted with 3 moles Na2CO3 so the ratio of the moles is 2 is to 3 represented as 2:3
