Answer:

Mass = 427.05 g

Step-by-step explanation:

Given data:

Formula units of sodium chloride = 4.38 ×10²⁴

Mass of NaCl = ?

Solution:

One mole contain formula units = 6.022 ×10²³

4.38×10²⁴ formula units × 1mol /6.022 ×10²³ formula units

0.73 ×10¹ mol

7.3 mol

Mass of NaCl:

Mass = number of moles × molar mass

Mass = 7.3 mol × 58.5 g/mol

Mass = 427.05 g
