Answer:

1. Source of carbon  

2. Removal of cuticle

Explanation:

You may have been doing a photosynthesis lab in a biology course.

1. NaHCO₃

The purpose of creating a sodium bicarbonate solution was to provide the carbon that the plant needs for photosynthesis.

2. Soap solution

The soap solution acted as a detergent.  It removed some of the waxy, water-repelling cuticle from the leaf's surface and made it easier for the sodium carbonate solution to get inside.

How many moles of Ag+ ions are present in 10 ml of a 0.75 M AgNO3 solution?
lana66690 [7]

Answer:

b. 7.5 x 10^-3

Explanation:

To solve this problem we need to keep in mind the <em>definition of molarity</em>:

  • Molarity = moles of solute / liters of solution

With the above information in mind it is possible to calculate the moles of solute, given the volume (10 mL) and concentration (0.75 M) of the solution:

  • First we<u> convert 10 mL to L</u> ⇒ 10 mL / 1000 = 0.01 L

Then we <u>calculate the moles of AgNO₃</u>:

  • moles of solute = Molarity * Liters of solution
  • 0.01 L * 0.75 M = 7.5x10⁻³ mol AgNO₃

<em>One mole of AgNO₃ contains one mole of Ag⁺</em>, thus the number of Ag⁺ moles is also 7.5x10⁻³.
