Answer:
Explanation:
1 mol of methane = 6.02 * 10^23 molecules
6.70 mol of methane = x
Cross multiply
x = 6.70 * 6.02 * 10^23
x = 4.033 * 10^23 molecules.
Answer: the cell will absorb more water which can lead to haemolysis (rising and bursting of the cell)
Explanation:
Answer:
1.138158E24 atoms or 1.14 x 10^24 atoms
Explanation:
To find atoms/particles from moles you just want to convert using avogadro's number which is 6.022 x 10^23
1.89 mol x 6.022 • 10^23
———— = 1.138158E24 atoms
1 mol
so 1.138158E24 atoms or 1.14 x 10^24 for scientific notation
hope this helps :)
Answer:
The answer to your question is 432 g of CO₂
Explanation:
Data
CaCO₃ = 983 g
CaO = 551 g
CO₂ = ?
Balanced reaction
CaCO₃ (s) ⇒ CaO (s) + CO₂ (g)
This reaction is balanced, to solve this problem just remember the Lavoisier Law of conservation of mass that states that the mass of the reactants is equal to the mass of the products.
Mass of reactants = Mass of products
Mass of CaCO₃ = Mass of CaO + Mass of CO₂
Solve for CO₂
Mass of CO₂ = Mass of CaCO₃ - Mass of CaO
Mass of CO₂ = 983 g - 551 g
Simplification
Mass of CO₂ = 432 g
