Answer: 5.5 grams
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass ,contains avogadro's number of particles and occupy 22.4 L at STP.
To calculate the number of moles, we use the equation:
1 mole of weigh = 44 g
0.125 moles of weigh =
Thus mass of 2.8 litres of is 5.5 grams
