Hydronium is H+.
Hydroxide is OH-.
pH = 7.3
pH is a logarithmic scale, so the concentration of H+ is 10 raised to the negated pH.
[H+] = 10^-7.3
pOH = 14 - 7.3 = 6.7
[OH-] = 10^-6.7

The formula you will ought to resolve those issues is: # of moles= the load given (g) / the molar mass or molecular weight of a substance (g/mol) a million.) i'm uncertain the style you hit upon the molar mass of an ant. those form of issues in common terms artwork with molecule. besides the shown fact that it may be: (.50g) / molar mass of ant; the mass of one ant would be rather small while in comparison with that of the earth; without even calculating the moles of an any, im guessing it may be achievable to have one mole of ants proceed to exist the earth 2.) you ought to first calculate the molar mass of water (H2O) via including up their atomic weights: 2 (2x1-the atomic weight of two H atoms) + sixteen (the atomic weight of one O atom) = 18 additionally: rearranging the formula, # of grams = # of moles (mol) x molar mass (g/mol) so.. # grams of water in a single mole = (a million mol) x (18 g/mol) = 18 grams of water in a single mol, which isn't sufficient to swim in

[H+] = 10^-7.3 = 5.012 x 10^-8
[OH-] = 1.995 x 10^- 7
