Question

Рассчитайте массу хлора Cl2,если его количество составляет 2.5 моль. Найдите количество вещества, которое составляет 5,85 кг хлорида натрия NaCl. СРОЧНООО, С ПОЛНЫМ ОФОРМЛЕНИЕ ПОЖАЛУЙСТА

Answer 1

N (CI2)=2.5 моль
m (CI2)=Mn=71*2.5=177.5г

m (NaCI)=5.85г
n (NaCI)=m/M=5.85/58.5=0.1 моль

Answer 2

Calculation of Chlorine Mass (Cl2)

To calculate the mass of chlorine (Cl2) when the quantity is given in moles, we need to use the molar mass of chlorine. The molar mass of chlorine is approximately 35.45 grams per mole (g/mol) [[1]].

Given that the quantity of chlorine is 2.5 moles, we can use the following formula to calculate the mass:

Mass = Quantity (in moles) × Molar Mass

Substituting the values into the formula:

Mass of Cl2 = 2.5 moles × 35.45 g/mol

Calculating the result:

Mass of Cl2 = 88.625 grams

Therefore, the mass of chlorine (Cl2) when the quantity is 2.5 moles is approximately 88.625 grams.

Calculation of Sodium Chloride (NaCl) Quantity

To calculate the quantity of sodium chloride (NaCl) when the mass is given in kilograms, we need to use the molar mass of sodium chloride. The molar mass of sodium chloride is approximately 58.44 g/mol [[2]].

Given that the mass of sodium chloride is 5.85 kilograms, we can use the following formula to calculate the quantity:

Quantity (in moles) = Mass / Molar Mass

Substituting the values into the formula:

Quantity of NaCl = 5.85 kg × (1000 g / 1 kg) / 58.44 g/mol

Calculating the result:

Quantity of NaCl = 100.14 moles

Therefore, the quantity of sodium chloride (NaCl) when the mass is 5.85 kilograms is approximately 100.14 moles.
