Although it shouldn’t have happened, on a dive i fail to watch my spg and run out of air. if my buddy is close by, my best option is to another option is to if i’m in shallow water and the surface is closer than my buddy.
a ascend using my buddy's alternate air source / make a controlled emergency swimming ascent
b ascend using my buddy's alternate air source / make an buoyant emergency ascent
c make a normal ascent / ascend using my buddy's alternate air source
d make a controlled emergency swimming ascent / make a normal ascent

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
