1.1 micromoles

Explanation:

You should consider the equation

n=cv

where n is the number of moles (or micromoles), c is the concentration and v is the volume.

The question gives us a volume of 0.35L or 0.35dm3 (which are the same) and a concentration of 3.1×106M or 3.1×106moldm3.

Therefore,

n=0.35dm3×3.1×106moldm3=1.085×106mol

So we know there are 1.085×106mol Hg2Cl2 in the solution, which is about 1.1 micromoles of mercury(I) chloride, since there are 106micromols in a mol.
