Based on the two starting amounts of Cu and HNO₃, the amount of NO₂ produced should be 0.0944 moles.

Calculate the concentration (in molarity) of the gas if that gas were confined to the 250 mL of space in the flask.

Respuesta :

The concentration (in molarity) of the gas if that gas were sealed to the 250 mL of space in the flask is 0.3776 M.

How do we calculate the molarity?

Molarity of any substance is defined as the number of moles of solute present in per liter of the solution and it will be represented as:

M = n/V, where

n = moles = 0.0944mol

V = volume = 250mL = 0.25L

On putting values, we get

M = 0.0944 / 0.25 = 0.3776 M

Hence required molarity is 0.3776 M.
