Question

Help help help I’m horrible at this stuff mayyyn

Answer 1

Just remember that at STP, 1 mole of any ideal gas = 22.4 liters.

So, convert 100.00 g of NH3 to moles and multiply by 22.4.

100.00 g NH3 x 1 moles NH3/17.031 g = 5.8716 moles NH3

5.8716 moles NH3 x 22.4 liters/mole = 131.52 liters (to 5 sig. figs.)
