How do i get form J to kj/mol? I used 50ml of 1.0M of HCl and .55g of Mg in the reaction
q = m x c(s) x ΔT
m = 50g
c(s) = 4.184 J/ g °C, water
ΔT = 38.21 °C
q = 50 x 4.184 x 38.21
q = 7993.5 J
how to find the molar concentration of a soloution of phosphoric acid if 17.8 mL of it neutralizes 20.0 mL of 0.050 mol/L calcium hydroxide.
You titrated 1.740g of a solid unknown acid that wasdissolved in 100.0 mL of distilled water; the initial pH value was 2.5. You found that pH= pKa =4.2 when 12.50 mL of NaOH had been added. The concentration of the sodium hydroxide was 0.500M. Cal..
