The equivalent weights of X and Y are _________ g/equiv. H+ and g/equiv. −OH , respectively, for the following reaction: Z
X: benzoic acid
Y: calcium hydroxide
z: 2C6H5COOH + Ca(OH)2 →
2H2O + Ca(C6H5COO)2

1. Since one H was used from X (benzoic acid), then the equivalent weight is molar mass/1.
The equivalent weight for Ca(OH)2 is molar mass/2 since 2 OH^- were neutralized.
For benzoic acid that is about 122 and for Ca(OH)2 that is about 74/2 but you need to confirm those by looking up the exact molar masses.
