Which of the following factors is measured in units of moles?!
1 point
Pressure
Volume
O Amount
Temperature

Amount.

Explanation:

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

For example,

Consider the photosynthesis reaction.

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 6 g of carbon. The number of moles of carbon would be,

Number of moles = 6 g/ 12 g/mol

Number of moles = 0.5 mol

the answer is c.the valence of the atoms combine .
