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
<h2>Answer:</h2>
A.NH4Cl
<h2>Explanations:</h2><h2>How are buffer formed?</h2>
Buffers are formed by mixing an equal amount of weak base or acids and their corresponding salts.
Therefore in order to make a buffer with NH3 (a weak base), then a corresposding weak salt is required. A corresponding salt for the given base is NH4Cl
The volume of one mole of any gas at Standard Temperature and Pressure (1 atm and 0 degrees Celsius [273K]) is 22.4 L.
