Answer:
805.6 moles
Explanation:
Molarity = 1.52mL
Volume = 530mL
1.52 moles is present in 1mL,
1mL = 0.001L
1.52 moles = 0.001L
X moles = 0.53L
X = (1.52 × 0.53) / 0.001
X = 805.6moles
805.6moles is present in 530mL or 0.52L
Lower temperature
Let's verify
- Pressure=P
- volume=V
- Temperature=T
As per Boyles law

As per Charles law


So
At higher altitudes lower the pressure so lower the temperature
Answer: (B)
Explanation: Decreases the number of bases in the sequence.
