Answer:
C. 0.001 second
Explanation:
Millisecond is a subunit of a second.
Milli depicts a unit to the power of 10⁻³
So;
1 millisecond = 10⁻³ s
Therefore,
1 x 10⁻³ = 0.001s
The solution to this problem is choice C which is 0.001 second
Y you just don’t wanna see it lol I love you
Answer:
The answer to your question is 5.529 x 10²⁴ molecules of H₂O
Explanation:
4NH₃ + 5O₂ ⇒ 4NO + 6H₂O
6.12 mol ? molecules
Rule of three (proportions)
4 mol of NH₃ ------------------- 6 mol of H₂O
6.12 mol of NH₃ --------------- x mol of H₂O
x = (6.12 x 6) / 4
x = 36.72 / 4
x = 9.18 mol of H₂O
1 mol of H₂O ------------------ 6.023 x 10²³ molecules
9.18 mol of H₂O ------------- x
x = (9.18 x 6.023 x 10²³) / 1
x = 5.529 x 10²⁴ molecules
