2.71 x 10²² molecules of CO2 is equivalent to 2.71 x 10²² atoms.

<h3>What is number of molecules?</h3>

The number of molecules in an element is the combination of atoms in that element.

The number of molecules of an element can be calculated by multiplying the number of moles of that element by Avogadro's number, which is 6.02 × 10²³.

However, the number of molecules in a substance is equivalent to the number of atoms in that substance.

Therefore, 2.71 x 10²² molecules of CO2 is equivalent to 2.71 x 10²² atoms.

Honors Stoichiometry Activity Worksheet

Explanation: Here, we will be considering 1 cup is equal to 1 mol.

2 water + sugar + lemon juice → 4 lemonade

Moles of water present in 946.36 g of water $=\frac{946.36 g}{236.59 g/mol}=4 mol$

Moles of sugar present in 196.86 g of water $=\frac{196.86 g}{225 g/mol}=0.8749 mol$

Moles of lemon juice present in 193.37 g of water $=\frac{193.37 g}{257.83 g/mol}=0.7499 mol$

Moles of lemonade in 2050.25 g of water $=\frac{2050.25 g}{719.42 g/mol}=2.8498 mol$

As we can see that number of moles of lemon juice are limited.

So, we will consider the reaction will complete in accordance with moles of lemon juice.

1 mole lemon juice reacts with 2 mol of water,then 0.7499 mol of lemon juice will react with:

$\frac{2}{1}\times 0.7499 mol = 1.4998 mol$ of water

Mass of water used = 1.4998 mol × 236.59 g/mol=354.8376 g

Water remained unused = 946.36 g - 354.8376 g =591.5223 g

1 mole lemon juice reacts with mol of sugar,then 0.7499 mol of lemon juice will react with:

$\frac{1}{1}\times 0.7499 mol = 0.7499 mol$ of water

Mass of sugar used = 0.7499 mol × 225 g/mol = 168.7275 g

Sugar remained unused = 196.86 g - 28.1325 g

1 mole of lemon juice gives 4 moles of lemonade.

Then 0.7499 mol of lemon juice will give:

$\frac{4}{1}\times 0.7499 mol=2.996 mol$ of lemonade

Mass of lemonade obtained = 2.996 mol × 719.42 g/mol = 2157.9722 g

Theoretical yield of lemonade = 2157.9722 g

Experimental yield of lemonade = 2050.25 g

Percentage yield of lemonade:

$\frac{\text{Experimental yield}}{\text{theoretical yield}}\times 100$

$\frac{2050.25 g}{2157.9722 g}\times 100=95.00\%$

The percentage yield of lemonade is 95% and ingredient which remained unused were water and sugar.

julsineya [31]

Answer:

This question is incomplete

Explanation:

This question is incomplete but there are two parts to this question that can generally be answered without the missing parts.

(1) If a CO₂ molecule starts out surrounded by other CO₂ molecules, does this influence how quickly it will reach the other side of the leaf?

What controls how quickly a CO₂ molecule/molecules enter into the leaf to the other parts of a leaf is the stomata on the leaf. Stomata are tiny openings on a plant leaf that allows for gaseous exchange (the release of oxygen and the absorption of CO₂) in the leaf.

(2) Collisions influence how molecules move, but do molecules only collide with other molecules of the same substance? NO

One of the kinetic theory of gases states that gases collide with one another and against the walls of the container. <u>It should however be noted that, gas molecules of a particular substance can collide with gas molecules of other substances</u>, so far they are within the same container.
