Homework Help: chemistry

Posted by nicole on Monday, October 25, 2010 at 5:25pm.

i am calculating an unknown acid for both monoprotic and diprotic assumptions. I calculated the monoprotic by multiplying the M NaOH by the liters of NaOH used to titrate. 0.0984M x 0.02396= 0.00236. I then take the unknown sample weight and divide it by the previous number to get the g/mol. so 0.177 g/0.002356= 75.13 g.mol? is this correct for monoprotic? and for diprotic do i just multiply the NaOH answer by 2 and take the unknown sample and divide it by the new NaOH amount?
