$Concentration = \frac{Moles}{Volume}$ $"Concentration"="Moles"/"Volume"$ . I get a mass of under $3 \cdot g$ $3*g$ .

Hence $\frac{mass}{molar mass} = moles = volume \times concentration$ $"mass"/"molar mass"="moles"="volume"xx"concentration"$

And thus.........

$mass = volume \times concentration \times molar mass$ $"mass"="volume"xx"concentration"xx"molar mass"$

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

Is this method clear enuff?
