Answer:

(B). 0.5

Step-by-step explanation:

No. of equivalents : Mass/equivalent mass ---{1}

Mass given to us is 10g. hence we need to find equivalent mass of Ca2+...

eq mass = Molar mass/valence factor = 40/2 = 20 ---{2}

since valence factor(or 'n' factor) is 2, and molar mass is 40

putting value of eq mass from {2} to {1},
we get,

No. of equivalents : 10/20 = 0.5
