Answer:

0.657 grams of Sodium chloride.

Step-by-step explanation:

Isotonic saline or normal saline contains 9 grams per litre of sodium chloride.

For 73 mL of isotonic saline :

1000 mL of isotonic solution contain 9 grams of NaCl

1 mL of isotonic solution contain
$(9)/(1000) \\\\$ grams of NaCl

73.0 mL of isotonic solution contain
(9*73)/(1000) = 0.657 grams of NaCl
