Given the following equation 2h2o —> 2h2 + o2 what mass of oxygen would from 2.30 moles of water?

 The mass  of oxygen  that would  formed   from 2.30  moles of water is  36.8  grams

     calculation

2H2O → 2H2 + O2

Step 1: find the moles of O2  using the mole ratio

The mole ratio  of H2O :O2    is 2:1 therefore  the moles of O2

     = 2.30  moles  x  1/2 =1.15 moles

Step 2:   find the mass of O2

mass=  moles  of O2  x molar mass  of O2

from periodic table the molar mass of O2  =16 g/mol  

since there  is 2 atom of Oxygen  the  molar mass =  16 g/mol  x2 =   32 g/mol

mass is therefore= 1.15 moles  x 32 g/mol= 36.8 grams

catya that's not even a b or c

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.
