A thin layer of gold was placed on a tray that measured 27.75 cm by 14.25 cm. The mass of the tray increased by 0.0624 g during the process. The density of gold is 19.32 g/cm3 . Calculate the thickness of the plating. I have very little idea as to how to go about solving this, and I need it for a chemistry assignment. Thanks

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
