1 milliliters in one milligram.
If one starts with 0.020 g of Mg, 0.0008 moles of H2 would be made if the reaction is complete.
Going by the balanced equation of reaction in the image, 1 mole of Mg will produce 1 mole of H2 in a complete reaction.
If 0.020 g of Mg is started with:
mole of Mg = mass/molar mass
= 0.020/24.3
= 0.0008 moles
Since the mole of Mg to H2 is 1:1, thus, 0.0008 moles of H2 will also be made from the reaction.

Answer:
0.8988
Explanation:
To calculate the fractional saturation of hemoglobin , the formula used is
YO_2=
now putting the values
YO_2= 
= 
=0.8988
Therefore, fractional saturation of hemoglobin= 0.8988
where
YO_2= fractional saturation of hemoglobin
pO_2= partial pressure of oxygen
p50= is the pO_2 at which hemoglobin is 50% saturated
