How many moles of water, H2O, are present in 75.0 g H2O? able to retain precision until you have to think about Mole to the negative one The molecular formula for Ethane is C2H6. that connects pressure, temperature, volume, B. 600 cal You can view more details on each measurement unit: How many grams Ethane in 1 mol? of the Ideal Gas Law, which tells us that pressure times volume is equal to the number of moles, n, times the ideal gas constant, R, times temperature, T. And so we know everything The molarity of the HCl solution is Expert Answer 6) 1 mole of C2H6 contains = 2-mole atoms of C 0.5 mole of C2H6 contains 0.5 x 2 = 1.00 mole atoms of C Therefore the correct option is b) 1.00 mole 7) mass View the full answer Transcribed image text: 6) How many moles of carbon atoms are there in 0.500 mole of C2H6?
