Detailed Solution
Download Solution PDF- हीलियम के ग्राम की संख्या (he) = 60 ग्राम
- आणविक द्रव्यमान कुल प्रोटॉन और न्यूट्रॉन का योग है।
- हीलियम का आणविक द्रव्यमान = 2 × 2 = 4
- अब द्रव्यमान को तत्वों की संख्या से गुणा करने पर हमें प्राप्त होता है = 4 × 1 = 4
- एक मोल अणु के कुल द्रव्यमान के बराबर है।
- हम जानते हैं कि एक मोल हीलियम अणु के 4 ग्राम के बराबर है।
- अब 60 ग्राम हीलियम में मोल की संख्या (n) = 60/4 है
इसलिए, n = 15 मोल
- 60 ग्राम में मोल की संख्या 15 मोल होगी।
