Question

В 70г воды расстворили 3,36л HCI вычислите HCI в расстворепожалуйста решите срочно

Answer 1

N(HCl)=V(HCl)/Vm=3,36л/22,4л/моль=0,15 моль
m(HCl)=n(HCl)*M(HCl)=0,15моль*36,5г/моль=5,475 г
w(HCl)=m(HCl)/m(p-p)=5,475г/(5,475г+70г)≈0,07254 (7,254%)

Answer 2

Calculating the Concentration of HCl in the Solution

To calculate the concentration of HCl in the solution, we can use the formula:

Concentration (in mol/L) = amount of solute (in mol) / volume of solution (in L)

Given: - Amount of water = 70 g - Amount of HCl = 3.36 L

First, we need to convert the amount of water from grams to liters. The density of water is approximately 1 g/mL, so 70 g of water is equal to 70 mL, which is 0.07 L.

Now, we can calculate the concentration of HCl in the solution using the given values:

Concentration of HCl = 3.36 L / (0.07 L + 3.36 L)

Let's calculate the concentration.
