Question

In photosynthesis, plants use energy from the sun to produce glucose, c6h12o6 , and oxygen from the reaction of carbon dioxide and water.
6co2 + 6h2o --> c6h12o6 + 6o2
what mass, in grams, of glucose is produced when 3.00 mol of water react with carbon dioxide?

Answer 1

Answer: 324 g (to 3 sf)

Explanation:

Based on the coefficients of the equation, we know that when 3.00 mol of water is consumed, 3.00 mol of carbon dioxide is also consumed.

• The atomic mass of carbon is 12.011 g/mol.
• The atomic mass of oxygen is 15.9994 g/mol.

Thus, the formula mass of carbon dioxide is:

$6(15.9994)+12.011=108.0074$ g/mol.

Thus, 3.00 mol has a mass of (108.0074)(3.00)=324 g (to 3 sf)
