Answer:

Mass of Sucrose in given Solution is 401.8158 grams.

Explanation:

Given,

Molarity  of Sucrose Solution = 0.758 M.

Volume of Sucrose Solution(V) = 1.55 L.

To find the mass of Sucrose in the solution, we need to find the number of moles of Sucrose present in the given solution 0f 0.758 M.

c = 0.758 M

number of moles can be calculated using

n = c*V

n= 0.758*1.55  = 1.1749 moles

Then to convert no, of moles to mass, we can use the formula,

number of moles(n) = Mass(m)/Molar Mass(M)

The Molar mass of Sucrose C₁₂H₂₂O₁₁ is

Mass of Carbon Sucrose = 12*12 = 144  grams

Mass of Hydogen in Sucrose = 1*22 = 22 grams

Mass of Oxygen in Sucrose = 16*11 = 176 grams

Molar mass of Sucrose = 144 + 22 +176 = 342 grams.

Substituting the values in the formula,

number of moles(n) = Mass(m)/Molar Mass(M)

we get,

1.1749 = (m)/342 => m = 1.1749 *342 = 401.8158 grams.

<u>Chemistry</u>

<u>Atomic Structure</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis
<h3>Explanation:</h3>

<u>Step 1: Define</u>

30 g SiO₂ (sand)

<u>Step 2: Identify Conversions</u>

Molar Mass of Si - 28.09 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of SiO₂ - 28.09 + 2(16.00) = 60.09 g/mol

<u>Step 3: Convert</u>

  1. Set up:                                \displaystyle 30 \ g \ SiO_2(\frac{1 \ mol \ SiO_2}{60.09 \ g \ SiO_2})
  2. Multiply/Divide:                  \displaystyle 0.499251 \ mol \ SiO_2

<u>Step 4: Check</u>

<em>Follow sig figs and round. We are given 2 sig figs.</em>

0.499251 mol SiO₂ ≈ 0.50 mol SiO₂

olga nikolaevna [1]
<h3>Answer: Choice A)  0-7</h3>

Explanation:

If the pH is between 0 and 7, then we have an acid.

If the pH is between 7 and 14, then we have an alkaline base.

If pH = 7, then it's neutral.

Lelechka [254]

Answer:

The solution in beaker A is unsaturated

The solution in beaker B is saturated

Explanation:

A saturated solution is a solution that contains just as much solute as it can normally hold at a particular temperature. An unsaturated solution is a solution that contains less solute than it can normally hold at a particular temperature.

If more solute is added to a saturated solution, the added solute does not dissolve completely. However, if more solute is added to an unsaturated solution, the added solute dissolves.

Which of the following statements about the carbon cycle is NOT true?
nalin [4]

Answer:

Plants consume carbon through transpiration

Explanation:

In transpiration, plants lose water vapor through the stomata in their leaves. No carbon is involved in transpiration, which has an outbound direction. Nothing can be consumed through the stomata when vapor is going out of the plant. It´s like trying to get in through the exit.
