How many moles of Hydrogen do you need, if you have 7.8 mol of Nitrogen? N2 + 6H2 → 2NHG
A.1.3 mol H2
B.2.63 mol H,
C.23.17 mol H.
D.46.8 mol H,

What is the number of moles of chemical units represented by 9.03x10^24? and how do i show work? (dumb it down )

How to convert a density of 0.791g/cm3 to lb/ft3

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
