Ib yam nkaus, qhov molarity ntawm hno3 yog dab tsi?

Cov molarity ntawm nitric acid yog 0.116 mol/L.

Tom qab ntawd, lo lus nug yog, dab tsi yog qhov zoo ntawm 37% HCL? Yog li ntxiv 8.3 ml ntawm 37 % HCL rau 1 liter ntawm D5W lossis NS los tsim 0.1N HCL kev daws teeb meem 12M (tus 37 % HCL ) = 12 moles/L = 12 x 36.5 = 438 g/L = 438 mg/ml. 0.1 M x 36.5 = 3.65 g/L = 3650 mg.

Ib yam nkaus, tib neeg nug, qhov sib txawv ntawm 85% phosphoric acid yog dab tsi?
