At a certain temperature the rate of this reaction is first order in H3PO4 with a rate constant of 2.35s1:

2H3PO4(aq) P2O5(aq) + 3H2O(aq)

Suppose a vessel contains H3PO4 at a concentration of 1.18M. Calculate the concentration of H3PO4 in the vessel 0.520 seconds later. You may assume no other reaction is important.

Round your answer to 2 significant digits.
