Which of the following factors is measured in units of moles

Amount

Explanation:

In chemistry the mole is use to measure the amount of substance.

For example,

Consider the photosynthesis reaction. It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

Chemical equation:

6H₂O + 6CO₂ + energy  →   C₆H₁₂O₆ + 6O₂

it is known from balanced chemical equation that 6 moles of carbon dioxide react with the six moles of water and created one mole of glucose and six mole of oxygen.  So amount is taken in term of moles.

When amount is given in grams moles can be calculated form following formula.

Number of moles of substance = Mass of substance/ molar mass of substance.

Consider there are 14 g of oxygen. The number of moles of oxygen would be,

Number of moles = 14 g/ 16 g/mol

Number of moles = 0.875 mol

the answer is 0.42 is that is an option. this question provides no info
