Given 7.3 moles of Ethane Gas (C2H6) and Excess Oxygen, how many moles of CO2 would be produced in the following combustion reaction? Round to 1 decimal place. Assume 1 Mole Ethane = 30.07 g of Ethane 2C2H6 + 7O2 --> 4CO2 + 6H2O

200. ml of 3.00 m nacl solution is diluted to a final volume of 500. ml. what is the molarity of the final solution?

Calculate the number of moles of ethane in 100 grams
