Answer:
Mass = 3732.62 g
Explanation:
Given data:
Number of formula units = 8.53×10²⁴
Mass of sample = ?
Solution:
1 mole of any substance contain 6.022×10²³ formula units.
8.53×10²⁴ formula units ×1 mol / 6.022×10²³ formula units
1.42×10¹ mol
14.2 mol
Mass of magnesium phosphate:
Mass = number of moles × molar mass
Mass = 14.2 mol × 262.86 g/mol
Mass = 3732.62 g
