one million. you may desire to understand the temperature, by using fact the density of water relies upon on the temperature. 20C is wide-unfold as "room temperature", so assuming that's the temperature, you may desire to understand the density of water in pounds/gallon or some equivalent length. To complicate issues, are you using a US gallon or a united kingdom gallon? The density of water at 20C is approximately 0.9982071g/cm^3 or 998.2071kg/M^3, you will might desire to transform to pounds and gallons. 2. Multiply so the cm^3 cancels and the g finally ends up on precise. 115cm^3 * 7.86g/cm^3 = 903.9gcm^3/cm^3 cancel the cm^3 to get 903.9g. to place it yet in any different case, iron hundreds 7.86 grams consistent with cubic centimeter. you have a hundred and fifteen cubic centimeters, so in simple terms multiply 7.86 x a hundred and fifteen to get the respond in grams. playstation a gallon of water basically weighs 8.34 pounds at maximum density, that's at 4C.

CaO is calcium oxide, :P all i know ( : i dont have my chemistry textbook sorrrry :(
