Determine the number of molecules in 3.79 kilograms of the fictional compound Cs7(Cr5O3)4. Include the units, but do not write t
Karo-lina-s [1.5K]

Answer:

1.0555 * 10^24 molecules

Explanation:

Number of molecules = ?

Mass = 3.79  Kg = 3790 g

Molar mass of Cs7(Cr5O3)4 = 2162.25 g/mol

Number of moles = Mass / Molar mass

Number of moles = 3790 g / 2162.25 g/mol

Number of moles = 1.7528 mol

1 mol = 6.022 * 10^23 molecules

1.7528 mol = x

solving for x;

x = 6.022 * 10^23 *  1.7528

x = 1.0555 * 10^24 molecules

A 7.06% aqueous solution of sodium bicarbonate has a density of 1.19g/mL at 25°C what is the molarity and molality of the soluti
lilavasa [31]

<em>c</em> = 1.14 mol/L; <em>b</em> = 1.03 mol/kg

<em>Molar concentration </em>

Assume you have 1 L solution.

Mass of solution = 1000 mL solution × (1.19 g solution/1 mL solution)

= 1190 g solution

Mass of NaHCO3 = 1190 g solution × (7.06 g NaHCO3/100 g solution)

= 84.01 g NaHCO3

Moles NaHCO3 = 84.01 g NaHCO3 × (1 mol NaHCO3/74.01 g NaHCO3)

= 1.14 mol NaHCO3

<em>c</em> = 1.14 mol/1 L = 1.14 mol/L

<em>Molal concentration</em>

Mass of water = 1190 g – 84.01 g = 1106 g = 1.106 kg

<em>b</em> = 1.14 mol/1.106 kg = 1.03 mol/kg
