Mole Calculations 1

Mole Calculations 1. Chemical Calculations. Atoms and molecules are extremely small. If they are so small and so light, how can we weigh them?. We weigh large numbers of them. Avogadro took 1.00 g of the smallest atom (H) and determined how many H atoms there are in 1.00 g of H .

Limiting Reactant

Limiting Reactant. 1 frame and 3 wheels are needed to create one tricycle. If I have 10 frames and 12 wheels, how many tricycles can I make?. 4. I have excess frames. My wheels limit how many tricycles I can make. Limiting reactant is the reactant that is all consumed.

Problem 27, p 615

Problem 27, p 615. At 327 o C, the equilibrium concentrations are [CH 3 OH] = 0.15 M, [CO] = 0.24 M and [H 2 ] = 1.1 M for the reaction: CH 3 OH (g) D CO (g) + 2H 2 (g) Calculate K p at this temperature. Problem 31, p. 615.
