The percentage of an element M is 53 in its oxide of molecular formula

1.	The percentage of an element M is 53 in its oxide of molecular formula M_(2)O_(3). Its atomic mass is about
Answer» 45 9 18 27 Solution :100 g of metal oxide contains 53 g of metal, `:.` EQUIVALENT mass of element`=("Mass of element")/("Mass of oxygen") xx 8 = (53)/(47) xx 8 ~=9` `:.` ATOMIC mass `=` Equivalentmass of an element `xx` Valency `= 9 xx 3 = 27g`
