Question 8 of 20 What is the M_(r) of magnesium nitrate (Mg(NO_(3))_(2)) ? Give your answer to the nearest whole number. Enter your answer as a number I

The relative formula mass (Mr) of magnesium nitrate (\(Mg(NO_{3})_{2}\)) can be obtained by summing polymer masses of constituents; magnesium (Mg), nitrogen (N) and oxygen (O). Magnesium nitrate structure contains one magnesium atom (Mg), two nitrogen atoms (2N), and six oxygen atoms (6O). Consequently, you can calculate Mr like this: ( ). Given that magnesium has a relative atomic mass of 24.3, nitrogen 14, and oxygen 16, adopting standard accurate chemistry, you will sum up the multiplication results to get the solution.
