Answer:

#"Moles of lithium sulfite req'd..........."=(422.55*g)/(93.94*g*mol^-1)=#

Explanation:

#=(422.55*g)/(93.94*g*mol^-1)=4.50*mol#.

And since #"concentration"="moles"/"volume"#, we need the quotient..........

#"volume"="moles"/"concentration"=(4.50*mol)/(2.50*mol*L^-1)=1.80*1/L^-1#

#1.80*1/(1/L)=1.80*L#

In practice, water is quite an involatile material. You would not evaporate this quantity of water.
