Mass of 1.204 times 10^24 atoms of hydrogen is equal to

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)
