Determine the mass of CO2 gas produced when 8.24 g of NaHCO3 is added to a solution that contains 4.41 g of HCl.
hjlf

The mass of CO₂ gas = 4.312 g

<h3>Further explanation</h3>

Reaction

NaHCO₃ (s) + HCl (aq) → NaCl (aq) + H₂O (aq) + CO₂ (g)

Find limiting reactant

mol NaHCO₃

\tt \dfrac{8.24}{84,007 }=0.098

mol HCl

\tt \dfrac{4.41}{36.5}=0.121

Limiting reactant :  NaHCO₃ (smaller)

mol CO₂ = mol NaHCO₃ = 0.098

mass CO₂ :

\tt 0.098\times 44=4.312~g

How many moles of dinitrogen tetroxide (N2O4) are in 6.49 x 109 particles?
yan [13]

Answer: There are 1.08 \times 10^{-14} moles N_{2}O_{4} present in 6.49 \times 10^9 particles.

Explanation:

According to the mole concept, 1 mole of a substance contains 6.022 \times 10^{23} particles.

Hence, number of moles present in 6.49 \times 10^9 particles are calculated as follows.

No. of moles = \frac{6.49 \times 10^9}{6.022 \times 10^{23}} mol

                      = 1.08 \times 10^{-14} mol

Thus, there are 1.08 \times 10^{-14} moles N_{2}O_{4} present in 6.49 \times 10^9 particles.
