How many moles c2h5oh are in 34 g
WebA chemical reaction describes what occurs in a electronic change. To shows not all one kind but or the relative amounts away the substances involved in a change… WebA mole is any item that contains the same number of that item as the number of atoms in exactly 12 g of 12 C. This means that in 12 g of C there are exactly 6.022 x 10 23 atoms of carbon. Each atom of C has a mass of 12 amu's, which means that: Now we are getting somewhere. Ethanol is CH 3 CH 2 OH. Its total mass is 46 u:
