The CO2 that builds up in the air of a submerged submarine can be removed by reacting it with sodium peroxide. 2 Na2O2 (s) + 2 C
grandymaker [24]

Answer: The sodium peroxide needed per sailor in a 24 hr period is 674 grams.

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = 1.02 atm

V = Volume of gas = 150.0 ml = 0.15 L

n = number of moles  of carbon dioxide = ?

R = gas constant =0.0821Latm/Kmol

T =temperature =20^0C=(20+273)K=293K

n=\frac{PV}{RT}

n=\frac{1.02atm\times 0.15L}{0.0821 L atm/K mol\times 293K}=0.006moles

2Na_2O_2(s)+2CO_2(g)\rightarrow 2Na_2CO_3(s)+O_2(g)

According to stoichiometry:

2 moles of carbon dioxide require = 2 moles of sodium peroxide

Thus 0.006 moles carbon dioxide require= \frac{2}{2}\times 0.006=0.006 moles of  sodium peroxide

Mass of  sodium peroxide needed for 24 hour=moles\times {\text {Molar mass}}=0.006mol\times 78g/mol\times 24\times 60=674g

Thus sodium peroxide needed per sailor in a 24 hr period is 674 grams.
