Answer:
1.80 x 10^24 atoms
Explanation:
3moles × 6.022×10^23 atoms/mole
Answer:
0.7644 moles of H₂O
Explanation:
The balance chemical equation is as follow;
2 H₂O₂ → 2 H₂O + O₂
To solve this problem we will first calculate the moles of H₂O₂ as,
Moles = Mass / M/Mass
Moles = 26.0 g / 34.01 g/mol
Moles = 0.7644 mol
Secondly,
According to equation,
2 moles of H₂O₂ produces = 2 moles of H₂O
Hence,
0.7644 mol of H₂O₂ will produce = X moles of H₂O
Solving for X,
X = 2 mol × 0.7644 mol / 2 mol
X = 0.7644 moles of H₂O
