During photosynthesis, how many moles of water (H₂O) are needed to produce 150 grams of glucose
Nuetrik [128]

During photosynthesis, 5 moles of water are needed to produce 150 grams of glucose. The correct option is D.

<h3>What is photosynthesis?</h3>

It is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.

  • Step 1: Write the balanced equation for photosynthesis.

6 CO₂ + 6 H₂O ⇒ C₆H₁₂O₆ + 6 O₂

  • Step 2: Convert 150 g of C₆H₁₂O₆ to moles.

The molar mass of C₆H₁₂O₆ is 180.16 g/mol.

150 g × 1 mol/180.16 g = 0.833 mol

  • Step 3: Calculate the moles of water required to form 0.833 moles of C₆H₁₂O₆

The molar ratio of H₂O to C₆H₁₂O₆ is 6:1.

0.833 mol C₆H₁₂O₆ × 6 mol H₂O/1 mol C₆H₁₂O₆ = 5.00 mol H₂O

During photosynthesis, 5 moles of water are needed to produce 150 grams of glucose. The correct option is D.

A sample has an atomic number is 18 and atomic mass 33, what is the number of neutrons?
Ivenika [448]

Answer:

15 neutrons

Explanation:

the atomic mass shows the amount of neutrons and protons added together

the atomic number shows us how many protons they are (you can also find out how many electrons a element has by looking at its atomic number as it will have the same amount of protons)

so to find the amount of neutrons the sample has you have you subtract the atomic number which is the amount of protons from the mass number which tells us the amount of neutrons and protons added together but we only need the neutrons that's why we subtract it

33-18=15

A 55 mL bottle of 12 M HCl was diluted with water to a 2.5 M HCl solution. What is the final volume of the diluted acid?
Angelina_Jolie [31]

The final volume of the diluted acid that was initially in a 55 mL bottle of 12 M HCl and diluted with water to a 2.5 M HCl solution is 264mL.

<h3>How to calculate volume?</h3>

The volume of a solution can be calculated using the following formula:

C1V1 = C2V2

Where;

  • C1 = initial concentration
  • C2 = final concentration
  • V1 = initial volume
  • V2 = final volume

12 × 55 = 2.5 × V2

660 = 2.5V2

V2 = 264mL

Therefore, the final volume of the diluted acid that was initially in a 55 mL bottle of 12 M HCl and diluted with water to a 2.5 M HCl solution is 264mL.
