[quote=SoloSurViVOR]What is it?[/quote]

chemistry~ very easy, but i just don't get it

A solution of phosphoric acid had a density of 1.7g/mL and a purity of 48% by weight. What is its molarity?

[quote=SoloSurViVOR]The mocular mass of phosphoric acid is 98.0 g/mol.

moles = mass/weight of the mole

1.7 / 98 = 0.01735

molarity = moles/volume

volume is 1mL=0...[/quote]

i c~ thx~ got to get back to other hws~ bye for now~
