Our whole lab is confused, and I'd be very thankful for this. I'll be sure to give the 10 points to the answer.

Molarity = 1000 x d / MM you're able to or won't undergo in innovations this formulation, yet you certainly could easily undergo in innovations right here- one million liter of 37% HCl has a mass of 1190 g (1000 mL x one million.19 g/mL) 1190 g of 37% HCl is composed of 40 4.0 g HCl (1190 x 37%) moles of HCl = mass of HCl / MM (40 4.0 g / 36.40 5 g/mol = one million.208 mole) So molarity is one million.2 M (2 s.f.)

I don't know what Jay is talking about but Scott's answer is correct. The % refers to g solute/100 ml solution then you convert it to M. You obtain N by multiplying the molarity and the # of equivalents which in this case is 1 since there is one hydrogen. Too wordy, just go w/ scott's.

It's around 10N don't listen to these other guys
37g in 1000g = 1N
37% = 37g in 100g or 370g in 1000g
370/37 = 10N
HCl valence =1 so you don't have to worry about that

This is not that hard of a question - should we take a vote?

37g HCL in 100mL solution
37g HCl = 2.055 mol HCl
2.055 mol/mL
1mol=1equiv
