#"Concentration"="Moles"/"Volume"#. I get a mass of under #3*g#.

Explanation:

Hence# "mass"/"molar mass"="moles"="volume"xx"concentration"#

And thus.........

#"mass"="volume"xx"concentration"xx"molar mass"#

#1.500*cancelLxx0.0250*cancel(mol)*cancel(L^-1)xx74.09*g*cancel(mol^-1)=??g#

Is this method clear enuff?
