Question

At a certain temperature and pressure, 1 L of Co, gas weighs 1.36 8. What is the mass of 1 L of N, gas at the same temperature and pressure? mass of 1 L of N, 1.16

Answer 1

Answer to the following question number of gaseous substances (amount of According to Avogardo's hypothesis, total in atoms (molecules of a gas (amount of gase is directly proportional to the volume occupied by goy at constant temperature and pressure. At constant temperature (T) and Pressure (P), Avogardo's law can be expressed via the following formula, on van v V =k zk where, v= volume of a gas n = number of moles ka cesta When we consider two gaseous substance, then Vi (-k=constant) At certain T and P, s.v . = 1L = volume of co2 • mole wlar weight of log – weight of co₂(w) - 1.35g 2 molewlar weight of co, (m) 14gmoly = 44 gmoth, & weight of Co2 (W) = 135g = 0.0.31 mol volume of H₂ (Vg) = 1L & Let weight of M₂ = Wrz gram (M) Molecular weight of 2 - 28 gmoth & mole of M₂ (2) - WHz gram = Me moli 28 gram moll From equation ③ Vo2 - VAL = VrgXno - 1x x 0. 031 mol ne 7 12 - O2 Ik = 0.031 mol :: MM2 = L = 0.031 mol → Wn2=(28 80.031) mol gram mo19 = 0.868 gram 28 Hence mass of M₂ i 0,868 g
