Answer:
0.657 grams of Sodium chloride.
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 grams of NaCl
73.0 mL of isotonic solution contain = 0.657 grams of NaCl
Molar mass:
O2 = 16 x 2 = 32.0 g/mol Mg = 24 g/mol
<span>2 Mg(s) + O2(g) --->2 MgO(s)
</span>
2 x 24.0 g Mg -------------> 32 g O2
5.00 g Mg -----------------> ( mass of O2)
mass of O2 = 5.00 x 32 / 2 x 24.0
mass of O2 = 160 / 48
= 3.33 g of O2
hope this helps!
