For H2SO4 we have a total of 32 valence electrons. Put a pair between the atoms. We're forming chemical bonds here. We've used 8, 10, 12, and then around the outside to fill the octets on the Oxygens, 14, and 32.So this looks like a pretty good Lewis structure for H2SO4. In the H 2 SO 4 Lewis structure Sulfur is least electron electronegative atom and goes in the center of the Lewis structure. 2  When we have an H (or H2) in front of a polyatomic molecule (like CO 3, SO 4, NO 2, etc.) we know that it's an acid.
18 g of water. The formula is H2O It is also 1 mole of water. Remember the Avogadro number 6.022 x 10 ^23, this is the number of molecules in one mole. Since in one molecule of water, there is only one oxygen atom, then there will be 6.022 X 10^23 atoms of oxygen present in 1 mole of water (18 grams).ater is H2O 1mol H2O contains 1 mol O atoms Molar mass H2O - 18g/mol You have 1.0 mol H2O This contains 1 mol O atoms 1mol atoms = 6.022*10^23 atoms (Avagadro's number) Answer: 18g H2O contains 6.022*10^23 O atoms. Positive: 61 %.
