btw...following c2=c1 x v1/v2, my calculations are out,

I meant 0.029 M x 0.6 ml /40.6 ml
= 0.00043 mol/L
=0.43 mM

so is this right for B: c1 x v1 = c2 x v2 c1=1% v1=0.6 c2=what we find v2=40.6 MW of lactose =342.3g/mol 1%= 1g/100ml = 10g/L =10g/342.3g/mol =0.029 mol/L c2=c1 x v1/v2 = 0.029 M x 0.6 ml / 40.6 ml = 0.0043 mol/L =0.43 ┬ÁM Is that correct? Should the concentration be expressed like that? Also, I'm ha...
