Answer : The mass of helium added to the cylinder was, 1.5 grams
Explanation :
Avogadro's law : It is defined as the volume of gas is directly proportional to the number of moles of gas at constant pressure and temperature.
or,
where,
= initial volume of gas = 2.00 L
= final volume of gas = 3.50 L
= initial moles of gas =
= final temperature of gas = ?
Now put all the given values in the above equation, we get:
Now we have to calculate the mass of helium were added to the cylinder.
Mass of helium added = 3.5 - 2.00 = 1.5 g
Thus, the mass of helium added to the cylinder was, 1.5 grams
