Answer:
volume = 13097674418.528dm³
Explanation:
n = (3.52)*10^32/(6.02)*10^23)
n = (584717607.97)
n = volume /molar volume
molar volume at stp = 22.4dm³
volume= 584717607.97 x 22.4
volume = 13097674418.528dm³
Answer:
6.022 x 1023 molecules = 1 Mole O2 = 22.4L
3.022 x 1023 molecules = 1/2 Mole O2 = 11.2L
The answer is 11.2 Litres
Explanation:
Answer:
3.66 moles of Zinc Oxide are consumed
Explanation:
Based on the reaction:
C + 2ZnO → 2Zn + CO₂
<em>Where 1 mole of Carbon reacts with 2 moles of Zin Oxide to produce 2 moles of Zinc and 1 mole of Carbon Dioxide.</em>
<em />
To solve this question, we must convert the moles of carbon added to the moles of Zinc Oxide that react using the chemical equation (1mol C = 2mol ZnO):
1.83 moles C * (2mol ZnO / 1mol C) =
<h3>3.66 moles of Zinc Oxide are consumed</h3>
