Predict the ion formed by each element: (a) Rb (b) K (c) Al (d) O

Density = mass (REMEMBER THIS FOR EXAM) volume * liquids typically * g OR g cm^3 ml (REMEMBER THESE FOR EXAM) Example 1: 55.00 gallons. When it is full of water, what mass of water does it contain 55.00 gallons 4 q x 46 ml x1.00 x1 lb= 458.4140969 lbs =6 x 10^1 lbs. 1 gall 1 qt 1 ml 454 g Example 2: Density = .897 g/ml Oil 55 gallon drum. What is the mass of the oil 55 gallon 4 qt x946 ml x.897 g= 186683.64 grams = 9 x 10^4 grams. 1 gall 1 qt 1 ml Example 3: Density = 11.3 g/cm^3 Size = 20.20 cm x 10.10 cm x 5.001,020.1 g Density of lead = 11.3 g/cm^3 1020.10 cm^3 x 11.3 x1 k x2.20 l= 5.4 lbs. 1 cm^3 10
