Answer:

Approx. #500*g#.................

Explanation:

We calculate the product...........

#2.5*cancelLxx1.00*cancel(mol*L^-1)xx194.19* g*cancel(mol^-1)=??*g#.

We have used the relationship:

#"Concentration"="Moles of solute"/"Volume of solution"#, and thus,

#"Moles of solute"="concentration"xx"volume of solution......."#
