Key Points संकल्पना:
- रेणू वस्तुमान म्हणजे रेणूमध्ये उपस्थित असलेल्या मूलद्रव्यांच्या अणू वस्तुमानाची बेरीज.
- ग्रॅममध्ये पदार्थाच्या एका मोलच्या वस्तुमानाला त्याच्या ग्रॅमरेणू वस्तुमान म्हणतात.
स्पष्टीकरण:
प्रत्येक मूलद्रव्यांच्या अणू वस्तुमानाचा त्याच्या अणूंच्या संख्येने गुणाकार करून आणि त्यांना एकत्र जोडून ते प्राप्त होते.
1 मोल हायड्रोजन = 1 ग्रॅम
1 मोल ऑक्सिजन = 16 ग्रॅम
पाणी (H2O) = 2 हायड्रोजन अणू + 1 ऑक्सिजन अणू
2 मोल हायड्रोजन = 2 ग्रॅम
1 मोल ऑक्सिजन = 16 ग्रॅम
हायड्रोजनच्या वस्तुमानाचे गुणोत्तर: ऑक्सिजनच्या वस्तुमानाचे गुणोत्तर = 2/16 = 1/8
हायड्रोजनच्या वस्तुमान आणि ऑक्सिजनच्या वस्तुमानाचे गुणोत्तर नेहमी 1:8 असते.
