Answer:
2.53×10²³ atoms
Explanation:
To solve this, convert grams to moles and moles to atoms.
To convert grams to moles, use the molar mass of C₁₂H₂₂O₁₁ (342.296 g/mol). Divide the mass by the molar mass to get moles. Moles = 0.4207
To convert moles to atoms, use Avogadro's number (6.022×10²³ atoms/mol). Multiply moles by Avogadro's number to get atoms. Atoms = 2.53×10²³
The idea of electric field was presented by Michael Faraday. The electrical field constrain acts between two charges, similarly that the gravitational field compel acts between two masses.

Answer:
Mass = 19.78 g
Explanation:
Given data:
Mass of NO produced = ?
Mass of NO₂ reacted = 60.0 g
Solution:
Chemical equation:
3NO₂(g) + H₂O(l) → 2HNO₃(g) + NO(g)
Number of moles of NO₂:
Number of moles = mass/molar mass
Number of moles = 60.0 g/ 46 g/mol
Number of moles = 1.3 mol
Now we will compare the moles of NO₂ with NO.
NO₂ : NO
3 : 1
1.3 : 1/3×1.3 = 0.43 mol
Mass of NO:
Mass = number of moles × molar mass
Mass = 0.43 mol × 46 g/mol
Mass = 19.78 g
