Anewly discovered metalloprotein, which contains three atoms of cd per molecule of protein, is found to be 0.782% cd by mass. calculate the molar mass of the metalloprotein.

 42966.7 g/mol

Explanation: As 1 molecule of protein contains 3 atoms of Cd.

1 mole of protein contains==3 moles of Cd.

1 mole of Cd weighs= 112 g

3 moles of Cd weigh=

Given: 0.782% of Cd is present by mass. Thus if x is the molar mass of protein,

it is the most commonly accepted one
