The solution for this problem would be:
H + ions from pH = 4.0 x 10^-4 moles.
But H2SO4 gives off 2 moles of H+ ions / mole.
Moles of H2SO4 = 2.0 x 10^-4
Mass = 2 x 10^-4 moles x 98 = 1.96 x 10^-3 grams
1.96 x 10^-3 grams / 10^3 = 1.96 x 10^-6 Kg.
There are 3 significant figures in 20600.
Glucose is C6H12O6.
so u simply need to add the individual masses of 6 carbons, 12 hydrogens and 6 oxygens.
the molecular mass of carbon is 12 but if u take it as 40..
them it would be..
6x40+12x1+6x16= whatever u get in your calc. ;)
Because the base is strong, and the acid is weak, the final solution will have a pH greater than seven. This is because the base disassociates more than the acid does. There are more OH- ions than H+ ions.
