1.	A sample of pure Ca metal weighing 1.35 grams was quantitatively converted to 1.88 grams of pure Cao. What is the atomic weight of Ca? (O = 16)
Answer» <html><body><p></p>Solution :From the formula of Cao,<br/> we know, moles of <a href="https://interviewquestions.tuteehub.com/tag/ca-375" style="font-weight:bold;" target="_blank" title="Click to know more about CA">CA</a> = moles of O <br/> `("weight of Ca")/("atomic wt. of Ca")= ("weight of O")/(" atomic wt. of O")` <br/>`(1.35)/(at. wt. of Ca.) = ( 1.88 - 1.35)/(<a href="https://interviewquestions.tuteehub.com/tag/16-276476" style="font-weight:bold;" target="_blank" title="Click to know more about 16">16</a>)` <br/>Atomic weight of Ca = 40-75.</body></html>
