Thank you for your reply. The Zn in grams 1.80= .028 moles Zn and Cl in grams 0.90= .025 moles Cl The question was: What is the EXPERIMENTAL empirical formula of zinc chloride? Determine the simplest whole number ratio of moles of
Which of the following effects will make the ratio (PV) / (nRT) less than 1 for a real gas? a) The gas molecules are large enough to occupy a substantial amount of space. b) A large number of molecules have speeds greater than the
How do you find out the number of moles in a certain amount of grams of a element or compound. After that, how do you find the number of atoms/molecules in that element or compound. Thanks grams/molar mass = # mols There are 6.02
I have absolutely no clue how to approach this question please help. The destruction of the ozone layer is an issue that is being discussed all around the world. Freons, or chlorinated hydrocarbon molecules, are very stable on the
