name: suggested answers date: _____ mole conversions - practice problems It is important to be able to convert between units of mass and volume measurement and ‘moles.’ The mole is a unit for counting atoms and molecules representing 602,000,000,000,000,000,000,000 particles. This is often written asIf we are given the number of atoms of an element X, we can convert it into moles by using the relationship. 1 mol X = 6.022 ×1023 X atoms. 1 mol X = 6.022 × 10 23 X atoms.

The Key to Balancing Chemical Equations. The ultimate goal for balancing chemical equations is to make both sides of the reaction, the reactants and the products, equal in the number of atoms per element. This stems from the universal law of the conservation of mass, which states that matter can neither be created nor destroyed.

1) write down the different elements in each compound. 2) write down how many of that particular atom there are 3) how many atoms are there total in the compound. Examples: A) MgCl2 Mg - 1 B) 5 ZnSO4 Zn - 5 Cl - 2 3 total S - 5 30 total O - 20 1) NaOH 2) 4 HNO3 3) MgCl2 4) 4 Li2O 5) 2 NaOH 6) Li2SO4 7) 3 H2O 8) NaC2H3O2 9) 3 Al2O3

1 × 2 = 2. 2 = 2, yes. These coefficients yield equal numbers of both H and O atoms on the reactant and product sides, and the balanced equation is, therefore: 2H 2O → 2H 2 + O 2.
