**Task:**

Carbon dioxide, $\mathrm{CO}_{2}$ is added to a tank containing nitrogen at 2.00 atmospheres and oxygen at 1.00 atmosphere until the total pressure within the tank is 4.6 atmosphere what is the partial pressure of the $\mathrm{CO}_{2}$?

**Answer:**

According to Dalton's Law, in a mixture of non-reacting gases a total pressure is equal to the sum of partial pressures of individual gases.

$$P = \sum_{i=1}^{n} p_i$$ $$p(\mathrm{CO}_2) = P - (p(\mathrm{N}_2) + p(\mathrm{O}_2))$$ $$p(\mathrm{CO}_2) = 4.6 - (2 + 1) = 1.6\,\mathrm{atm}$$
