Volume is the thing
…………….
I think it is because it has an even number of valence electrons.
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
∴ B is the Answer
Answer:
50kg
Explanation:
Using the formula for potential energy, which is the amount of energy due to position;
P.E = m × g × h
Where;
m = mass (kg)
g = acceleration due to gravity (10m/s²)
h = height (metres)
According to the information provided in this question, m = ?, P.E = 2500J, h = 5m
Using P.E = m × g × h
m = P.E/gh
m = 2500/(5 × 10)
m = 2500/50
m = 50kg
The mass of the man is 50kg.
