Chemistry

Answer:

mass of CO₂ = 5.402 g

Explanation:

At STP, 1 mole of any gas takes up 22.4L of volume

Thus, 1 mole = 22.4 L

1 L = 1 mole ÷ 22.4

Therefore, 2.75 L = 2.75 mole ÷ 22.4 = 0.123 moles

Molecular weight of CO₂ = 44 g/mole

mass of CO₂ = molecular weight * number of moles = 44 g/mole * 0.123 moles

mass of CO₂ = 5.402 g

Answer:

Why do most atoms form chemical bonds? They want a full outer shell of electrons, so the lose, gain, or share electrons with other elements, forming compounds, until they have 8 valence electrons and become stable. Double and triple covalent bonds that have greater bond energy and are shorter than single bonds.
