Answer:

19 g

Explanation:

Data Given:

Sodium Chloride (table salt) = 50 g

Amount of sodium (Na) = ?

Solution:

Molecular weight calculation:

NaCl = 23 + 35.5

NaCl = 58.5 g/mol

Mass contributed by Sodium = 23 g

calculate the mole percent composition of sodium (Na) in sodium Chloride.

Since the percentage of compound is 100

So,

Percent of sodium (Na) = 23 / 58.5 x 100

Percent of sodium (Na) = 39.3 %

It means that for ever gram of sodium chloride there is 0.393 g of Na is present.

So,

for the 50 grams of table salt (NaCl) the mass of Na will be

mass of sodium (Na) = 0.393 x 50 g

mass of sodium (Na) = 19 g

How many atoms of mercury are required to produce 3.49 L of H2 gas (density =
Setler79 [48]

The number of mercury atoms required to produce 3.49 L of H2 gas according to the equation would be 1.89 x 10^{23}

From the balanced equation of the reaction:

2Hg(l) + 2 HNO_3(aq) ---> Hg_2(NO_3)_2(aq) + H_2(g)

2 moles of Hg are required to produce 1 mole of the H2 gas.

3.49 L of H2 gas was produced and the density of the gas is 0.0899 g/L

Recall that: density = mass/volume

Mass of the H2 gas = density x volume

                                     = 3.49 x 0.0899

                                     = 0.3138 g of H2 gas

Mole of 0.3138 g of H2 gas = mass/molar mass

                                         = 0.3138/2

                                            = 0.1569 mole

Since the ratio of Hg to H2 according to the equation is 2:1, it means that the mole of Hg is twice the mole of H2.

Thus, mole of Hg = 0.1569 x 2

                                    = 0.3138 mole

According to Avogadro, 1 mole of a substance = 6.022×10^23

0.3138 mole would be:

                 0.3138 x 6.022 x 10^23

                            = 1.89 x 10^{23}

The mole fraction of iodine, i2, dissolved in dichloromethane, ch2cl2, is 0.115. what is the molal concentration, m, of iodine i
german
The molality of a solute is equal to the moles of solute per kg of solvent. We are given the mole fraction of I₂ in CH₂Cl₂ is <em>X</em> = 0.115. If we can an arbitrary sample of 1 mole of solution, we will have:

0.115 mol I₂

1 - 0.115 = 0.885 mol CH₂Cl₂

We need moles of solute, which we have, and must convert our moles of solvent to kg:

0.885 mol x 84.93 g/mol = 75.2 g CH₂Cl₂ x 1 kg/1000g = 0.0752 kg CH₂Cl₂

We can now calculate the molality:

m = 0.115 mol I₂/0.0752 kg CH₂Cl₂
m = 1.53 mol I₂/kg CH₂Cl₂

The molality of the iodine solution is 1.53.
