i still don't know what i am still missing in the process of finding the answer. do i times it by 1000mL to cancel out the mL from the density or what? I am totally lost.
Homework Statement
one gallon of octane is equivalent to 23.4 mol of octane. the density of it is .703g/mL.

Homework Statement
An alloy sample weighing 5.00g contains Cr. The Cr is chemically converted to a K2Cr2O7 solution. The Cr2O7^-2 ion in the solution is converted to Cr^+3 by reacting it with 4.73g of I2.
Cr2O7^-2 + I2 --->Cr^+3 +IO3 ( need to balance redox reaction)
