<u>Answer:</u> The molar mass of metal (M) is 47.86 g/mol
<u>Explanation:</u>
Let the atomic mass of metal (M) be x
Atomic mass of
To calculate the mass of metal, we use the equation:
Mass percent of metal = 59.93 %
Mass of metal = x g/mol
Mass of metal oxide = (x + 32) g/mol
Putting values in above equation, we get:
Hence, the molar mass of metal (M) is 47.86 g/mol
