Answer:
6:7
Step-by-step explanation:
To calculate hydronium concentration from pH, type on you calculator
10 to the power of negative pH value
10^-5.5 = 3•10^6 mol/L
Since there are 3 hydrogens in every hydronium molecule,
There are 9 • 10^6 hydrogens in that liter of acid.
93.6
78*0.20=15.6
78+15.6=93.6
(89000 + 3000) - (35000 + 4902 + 4000) = $48,098 (this is the amount you owe taxes on). I can't see the tax table, but generally speaking, your adjusted income is what you pay taxes on (notice my wording), so you should multiply the $48,098 by the percentage associated with the adjusted income. I hope this helps.
49-17.50 then add that with 5 then add it in a promotion
