Answer:
1 Oxygen atom has a mass of 16 grams, thus diatomic oxygen weights twice as much- 32 grams. Hence 32 grams is needed.
Because they do not have the same qualities therefore they are different
Mass = 5 g
volume = 20 cm³
density = mass / volume
therefore:
D = m / V
D = 5 / 20
D = 0.25 g/cm³
The electric field, or any field such as magnetic field or gravitational field, is the strongest the closer we get to the source of the field. The concentration of field lines also increases closer to the object; these field lines are seen to be coming out of a positive charge.
Therefore, the strongest electric field is at the point where the concentration of electric field lines is the highest.
Answer:
Explanation:
Mole = no. Molecules/6.02×10^23
Mole = (1.40×10^24)/(6.02×10^23)
Mole = 2.33mole
