Re: Determining mass for solutions

Molar mass of KCLO3 is 39 + 35.5 + 16(x3) = 122.5 = 122.5g per 1 mole solution Molar mass of KCLO3 for 0.5M solution = 122.5g divided by 2 = 61.25g per .5 mole solution

Re: Chemical equations

That's weird. This was the question the lecturer gave.
"Write an equation representing the solubility of sugar in the different solvents (3 marks)"

Re: Determining mass for solutions

yes, so I have to divide the moral mass in half to get the answer for .5 mol? and then add water?? I don't understand completely

Re: Determining mass for solutions

Molar mass of KCLO3 is 39 + 35.5 + 16(x3) = 125.5
= 125.5g/ 1 mole
this is what I have so far, what next?

Chemical equations

Hi everyone I have an assignment on the solubility of sugar in different liquids. How do I create/ what are chemical equations for
1) sugar + oil
2) sugar + rubbing alcohol
3) sugar + water



Thanks for helping
