Answer:
You could calculate the answer given the formula
M = mol/L
you can get mol using g/MolarMass
=> 42g/22.99g/mol = 1.82688125mol
1.25M = 1.82688125mol/V
=> apply simple algebra
V = 1.4615 L
=> Notice that the answer requires the unit to be ml
V = 1.4615L * 1000ml/L = 1461.5ml
=> Notice that the given grams have 2 sig figs
V = 1500 ml
