When a 1.50x102 g strip of zinc is dropped into a large beaker containing excess hydrochloric acid, how many grams of gas are formed?
A sample of gas (24.2 g) initially at 4.00 bar was compressed from 8.00 L to 2.00 L at constant temperature. After the compression, the gas pressure was ________ bar.
Also, at the end 1.31 g of 4,4-dimethyl-2-cyclohexen-1-one was obtained. My question how to calculate percent yield for 4,4-dimethyl-2-cyclohexen-1-one and theoretical yield for this lab.
