Because science have measurements.
This is an ionic precipitation reaction
Answer : The mathematical equation used when solving calorimetry problems is:

Explanation :
Calorimetry : It is determining the changes in the energy of a system by measuring the heat transferred with surroundings.
Formula used :

where,
c = specific heat capacity of calorimeter
m = mass of a substance
q = heat required
= change in temperature of substance

Answer:
650 grams
Explanation:
Given that acetylene gas reacts with oxygen to produce caobon dioxide, water and heat and the unbalnced equation is

Gram-formula mass of
g/mol
So, mass of 1 mole of acelylene is 26 grams
Therefore, mass of 25 moles of acelylene=25x26=650 grams
Hence, the mass of 25 moles of acelylene is 650 grams
