If we assume "sodium hydroxide" reacts with "sulfuric acid".....approx. 90*g "sodium sulfate" results......

Explanation:

We write the equation as:

2NaOH(aq) + H_2SO_4(aq) rarr Na_2SO_4(aq) + 2H_2O(l)

"Moles of sodium hydroxide"=(49.9*g)/(40.00*g*mol^-1)=1.25*mol.

The equation specifies that HALF an equiv of "sodium sulfate" results from neutralization, and this represents a mass of

1.25*molxx1/2xx142.04*g*mol^-1=88.8*g.
