The overall chemical reaction for photosynthesis isshown below: 6co2 + 6h20 → c6h12o6 + 602what mass of glucose (c6h1206) can form from71.89 g co2? (molar mass of c6h1206 = 180.18g/mol; molar mass of co2 = 44.01 g/mol)71.89 g co2=g c6h1206

Calculate the number of molecules present in 0.750 mol of mgo.

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
