Q: 92 (NDA-II/2016)How many moles of hydrogen atom are present in one mole of Aluminium hydroxide ?One mole Two molesThree molesFour moles0040010321140031990-20002001-20102011-2022hydrogen atom many moles aluminium mole molesKeyword HeatmapAnyChart Trial Versionquestion_subject: Sciencequestion_exam: NDA-IIstats: 0,38,47,18,27,38,2keywords: {'hydrogen atom': [0, 0, 0, 4], 'many moles': [0, 0, 0, 1], 'aluminium': [1, 0, 3, 2], 'mole': [1, 1, 1, 4], 'moles': [0, 0, 0, 3]} Explanation The correct answer is option 3: Three moles. To understand this, let`s first break down the formula of Aluminium hydroxide (Al(OH)3). In one mole of Aluminium hydroxide, we have one mole of Aluminium (Al), and three moles of hydroxide (OH). The hydroxide group (OH) consists of one oxygen atom (O) and one hydrogen atom (H). So, in one mole of Aluminium hydroxide, we have 3 moles of hydrogen atoms. Therefore, option 3: Three moles, is the correct answer. Please login to bookmark this question
