Anyone know the mwt of Phosphate Buffered Saline tablets?? Trying to get 0.1M PBS solution, with pH 6.8?

Question

I cant do this w/out knowing the mwt of the tablets (its not on the bottle or in the MSDS...). I cant just add tablets to acheive my pH cuz water has its own pH (which is probably around 6.8 too).

Answer 1

The chemicals used and their relative %ages must be on the cover. Use that ot calculate.
