a scientist prepares a solution by mixing 25ml of solution g with 50ml of solution h resulting in a solution with a mass of 125 grams . he then combined 45ml of solution g with 20 ml of solution h which procedures a solution with a mass of 120 grams in the equation below g represents the concentration of solution g and h represents the concentration of solution h .
what is the concentration of solution h , in grams/ml

what is the concentration of solution h , in grams/ml

anonymous · Answer

the equation is like this 25g+50h=125 and 45g+20h=120

Something seems weird to me about this question. It seems that g and h are not concentrations but density. Let me think it over

anonymous · Answer

ok

wolfe8 · Answer

But I guess if it says that, then solving the simultaneous equation should give you the concentrations for g and h.

anonymous · Answer

25g+50h=125     and  45g+20h=120

wolfe8 · Answer

Ah it makes sense now. This is a math question not really chemistry. I took it as being complicated. Just solve the simultaneous equation problem for h.

so i need to ask the math people

wolfe8 · Answer

Yes but since it's already here I'll help you. Are you familiar with the methods of solving them? You have substitution and elimination. http://www.allaboutcircuits.com/vol_5/chpt_4/11.html

anonymous · Answer

yes i know how to do them

wolfe8 · Answer

Right. So is there anything else you need help with?

anonymous · Answer

i dont know let me try again 2 do it
