Question:

Chem help!! calculating the volume of cation-exchange resin?

Can someone please show me how to do this problem? Sorry so longOne ten minute shower using a restricted-flow shower head (2.5 gal/min) requires 25 gal of water, and it has been estimated that each person uses about 60 gal a day. Calculate the volume of cation-exchange resin (in L) that would be required to remove all the water hardness in the water used by one person in 30 days at 60 gal/day. Assume that the exchange capacity of the resin is 1.7 meq/mL of resin and that the water hardness is equivalent to 200 mg CaCO3/L

Answer:

Try the Brooks Adrenaline GTS
The pressure in the tyre is directly proportional to the temperature of the air. Put simply, if the temperature increases (which will happen during an hours drive) then the pressure will also increase. Note that to calculate values the temperature must be in kelvin (0 kelvin 273 degrees celsius). You would then use P1/T1 P2/T2.
