Approx. 0.15*mol..........

Explanation:

"Concentration"="Moles of solute"/"Volume of solution"

To get one quantity or the other, we take the quotient or the appropriate product.

Adn thus "Moles of solute"="Concentration"xx"Volume of solution"

=0.745*mol*cancel(L^-1)xx189*cancel(mL)xx10^-3cancelL*cancel(mL^-1)=??*mol.

And thus the calculation was dimensionally consistent.
