If we were to see the bottom denominator as a bigger number, and also seeing the top numerator smaller then the denominator, this this would be a bigger fraction and also vice-versa. Lets first consider what would be (0.7) as a fraction. .7 would be noticed as 70%. But as a fraction, this would then be 7/10. Therefore, we would then have a newer order. And also for .6, this would be the same case.

By reforming this, it would then be the following:

7/10, 1/8, 1/2, 1/6, 4/5.

Your answer would then be below.

1/8 would be the smallest.

Then 1/6.

Then afterward, 1/2 would then be half.

Then the next ones would then be the fractions that are almost finished.

Then, 7/10, and therefore 4/5 as the last one.

Those would be the order from least to greatest.

What is the mass grams that are in 2.57 × 10²⁵ molecules of I₂
lina2011 [118]

The mass of I₂ that contains 2.57×10²⁵ molecules is 10843.52 g

From a detailed understanding of Avogadro's hypothesis, we understood 1 mole of any substance contains 6.02×10²³ molecules. This implies that 1 mole of I₂ also 6.02×10²³ molecules i.e

<h3>6.02×10²³ molecules = 1 mole of I₂</h3>

Recall:

1 mole of I₂ = 2 × 127 = 254 g

Thus,

<h3>6.02×10²³ molecules = 254 g of I₂</h3>

With the above information, we can obtain the mass of I₂ that contains 2.57×10²⁵ molecules. This is illustrated below:

6.02×10²³ molecules = 254 g of I₂

Therefore,

2.57×10²⁵ molecules = \frac{2.57*10^{25}  * 254}{6.02*10^{23}}\\\\

<h3>2.57×10²⁵ molecules = 10843.52 g of I₂</h3>

Thus, the mass of I₂ that contains 2.57×10²⁵ molecules is 10843.52 g

2. A solution is made by adding 1.23 mol of KCl to 1000.0 g of water. Assume that the
ladessa [460]

Answer:

a. 74.55 g/mol.

b. 91.70 g.

c. 8.40%.

d. 1.23 mol/L.

Explanation:

<em>a. Calculate the formula weight of KCl.</em>

∵ Formula weight of KCl = atomic weight of K + atomic weight of Cl

atomic weight of K = 39.098 g/mol, atomic weight of Cl = 35.45 g/mol.

∴ Formula weight of KCl = atomic weight of K + atomic weight of Cl = 39.098 g/mol + 35.45 g/mol = 74.548 g/mol ≅ 74.55 g/mol.

<em>b. Calculate the mass of KCl in grams.</em>

  • we can use the relation:

<em>no. of moles (n) = mass/molar mass.</em>

∴ mass of KCl = n*molar mass = (1.23 mol)*(74.55 g/mol) = 91.69 g ≅ 91.70 g.

<em>c. Calculate the percent by mass of KCl in this solution.</em>

The mass % of KCl = (mass of KCl/mass of the solution) * 100.

mass of KCl = 91.70 g,

mass of the solution = 1000.0 g of water + 91.70 g of KCl = 1091.70 g.

∴ The mass % of KCl = (91.70 g/1091.70 g)*100 = 8.399% ≅ 8.40%.

<em>d. Calculate the molarity of the solution.</em>

Molarity is the no. of moles of solute per 1.0 L of the solution.

<em>M = (no. of moles of KCl)/(Volume of the solution (L))</em>

no. of moles of KCl = 1.23 mol,

Volume of the solution = mass of water / density of water = (1000.0 g)/(1.00 g/mL) = 1000.0 mL = 1.0 L.

M = (1.23 mol)/(1.0 L) = 1.23 mol/L.
