Answer:
<h3>The answer is 1.02 g/cm³</h3>Explanation:
The density of a substance can be found by using the formula
From the question
mass of block = 25 g
volume = 24.5 cm³
The density of the block is
We have the final answer as
<h3>1.02 g/cm³</h3>Hope this helps you
CH₄ + 2O₂ → CO₂ + 2H₂O
From the equation, we know that methane and carbon dioxide have the same number of moles.
no. of moles of CO₂ produced = no. of moles of methane
= 4.5 × 10⁻³ ÷ (12 + 1×4)
= 2.8125 × 10⁻⁴
∴ mass of CO₂ = 2.8125 × 10⁻⁴ × (12 + 16×2)
= 12.375 × 10⁻³ g
