What is the mass of 2.50l of so2 gas at stp

4.84 grams

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass, occupies 22.4 L of volume at STP and contains avogadro's number of particles.

To calculate the number of moles, we use the equation:

1 mole of weighs = 44 g

0.11 moles of weigh =

Thus mass of 2.5 L of weigh 4.84 grams.
