How many grams of sucrose will I add to the water (0.100 L) in order to make the 3 molal solution.

Answers

Answer:

mass = 102.69 g of sucrose

Explanation:

First, you need to use the correct expression of molality (m) which is the following:

m = moles / kg solvent    (1)

According to the exercise, we need to get the grams, in other words, the mass of the sucrose. To get the mass, we need the moles and molecular weight of sucrose and use the following expression:

moles = mass / MM    (2)

Now, if we replace (2) in (1) we have:

m = mass / MM * kg solvent   (3)

From here, we solve for the mass and then:

mass = m * MM * kg solvent (4)

Now, then density of water is 1 kg/L, so, the volume of the water will be the same as it's mass, and the molality is 3 m. The molecular weight of the sucrose is (according to several sources) 342.3 g/mol. Replacing all the data in (4) we have:

mass = 3 mol/kg * 0.1 kg * 342.3 g/mol

mass = 102.69 g of sucrose

Hope this helps

Why is there an attraction between the two ions in this chemical bond?

Answers

Answer:

A metallic bond is a force of attraction between charged metal ions and the electrons that are in the delocalized bond, which covers the assembly of ions. A covalent bond is the force of attraction between the nuclei of atoms, and the electrons shared between them.

Explanation:

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond can be generated by electrostatic attraction between charged ions (for example, ionic bonds) or by electron sharing (for example, covalent bonds).

What is state of matter?

Solids, liquids, gases, plus plasma are the four states of matter that may be found in daily life. However, a number of additional states of matter have indeed been found.

Some of these additional states are created when a material transitions among two states of matter and doesn't actually exhibit the characteristics of either state. The most exotic are others. Both a volume and a definite form are absent from a gas. The separation of gas particles is great. The gas in a balloon and the air are two examples of gases.

Calculate the percentage composition of SrBr2

Answers

Answer:

64.6% of Br and 35.4% of Sr

Explanation:

The percentage composition is obtained defining the percentage in mass of each atom in a molecule.

To solve this question we must find the mass of each atom in 1 mole:

Molar mass Br: 79.904g/mol

Molar mass Sr: 87.62g/mol

The molar mass of SrBr2 is:

79.904g/mol*2 + 87.62g/mol =

159.808g/mol + 87.62g/mol =

247.428g/mol

The percentage of Br is:

79.904g/mol*2 = 159.808g/mol / 247.428g/mol * 100

= 64.6% of Br

And percentage of Sr is:

87.62g/mol / 247.428g/mol * 100

= 35.4% of Sr
