Answer:
A leaf needs carbon dioxide and water for photosynthesis. ... For carbon dioxide to enter, the stomata on the surface of the leaf must be open. As you have seen, transpiration draws water from the roots into the leaf mesophyll.

The number of mole of the gas present in the sample which occupies a volume of 350 mL at 25 °C and 1 atm is 0.0143 mole
From the question given above, the following data were obtained:
Volume (V) = 350 mL = 350 / 1000 = 0.35 L
Temperature (T) = 25 °C = 25 + 273 = 298 K
Pressure (P) = 1 atm
Gas constant (R) = 0.0821 atm.L/Kmol
<h3>Number of mole (n) =? </h3>
With the application of the ideal gas equation, the number of mole of the gas present in the sample can be obtained as follow:
<h3>PV = nRT </h3>
1 × 0.35 = n × 0.0821 × 298
0.35 = n × 24.4658
Divide both side by 24.4658
n = 0.35 / 24.4658
<h3>n = 0.0143 mole </h3>
Therefore, the number of mole of the gas present in the sample is 0.0143 mole
