Answer:
P = 8000 Kg m/s
When speed is increased to 50 m/s,
P = 40,000 kg. m/s
Explanation:
Given data:
Mass = 800 Kg
Velocity = 10 m/s
Momentum = ?
Speed increased = 50 m/s
Momentum = ?
Solution:
Formula:
P = mv
P = 800 kg× 10 m/s
P = 8000 Kg m/s
When speed is increased to 50 m/s.
P = mv
P = 800 kg× 50 m/s
P = 40,000 kg. m/s
The average mass of a single chlorine atom is 35.453 grams
Answer:
The number of moles = 0.06 moles
Explanation:
i) Formula
Number of moles = Mass of the sample ÷ Molar masses of the substances
ii) Number of moles = 10.0 ÷ (137)+(19×2)
= 10.0 ÷ 175
= 0.06 moles
