Zinc chloride calculation - I know this is stupid... but please help me! (Sep/28/2009 )
Hey peeps,
Sorry to have to bother you guys, but I'm always messing up at calculations so I thought it would be good for me to double confirm.
I want to make a solution of zinc chloride, and the bottle says it's 136.28g/mol.
Say.. I wanna make 250mM, so that means 0.25M.
So in ONE LITER, I am supposed to have 136.38g/mol X 0.25mole/L = 34.07g right?
If that is so... then in 50mL, I need 1.70g of zinc chloride!
Thanks in advance!!!!
