Atomic Weights

Atomic Weights. The mass of an individual atom, ion, or molecule is very small. Scientists use the atomic mass unit (amu) to express the mass of atoms or molecules. 1 amu = 1.66054 x 10 -24 g 1 g = 6.022 x 10 23 amu. Atomic Weight. Atomic weight (atomic mass) :

Determining the Formula of a Hydrocarbon by Combustion

Determining the Formula of a Hydrocarbon by Combustion. CCR, page 138. Using Stoichiometry to Determine a Formula. Burn 0.115 g of a hydrocarbon, C x H y , and produce 0.379 g of CO 2 and 0.1035 g of H 2 O . C x H y + some oxygen ---> 0.379 g CO 2 + 0.1035 g H 2 O
