0 min there are .065 moles of A

10 min there are .051 moles of A

20 min there are .042 moles of A

30 min there are .036 moles of A

40 min there are .031 moles of A

The total volume is 100.0 mL.

The equation given is: A -> B

I know that to get Molarity you divide the number of moles by the total volume in Liters (which means a conversion of mL to Liters). Also that minutes would have to be converted to seconds by multiplying by 60.

**bobpursley**, Friday, November 13, 2009 at 6:11pmI supspect the M in M/s is moles per second, not concentration decrease. No volume was specified. Frankly, if this is what is desired, it should have said mol/s . But I do think that is what it meant.

.014 moles disappeared in the first 600 sec, or an average rate of 6.67millimoles/sec
