1 g Ca was burnt in excess of O, and the oxide was dissolved in wate

1.	1 g Ca was burnt in excess of O, and the oxide was dissolved in water to make up one litre ofsolution. The normality of solution is(1) 0.04(2) 0.4(3) 0.05(4) 0.5
Answer» CORRECT option is:-(4) 0.05Explanation:We have,Ca+(1/2)O2→CaOCaO+H2O→Ca(OH)2Mass of calcium = 1gMoles of calcium = 401=0.0250.025 MOLES of calcium = 0.025 moles of Ca(OH)2n-factor = 2 for Ca(OH)2Normality =12×0.025=0.05NPLEASE MARK ME AS BRAINLIEST
