Question

32 gm of metal react with 48 gm of O2 find equivalent mass​

Answer 1

E= molecular mass /valency

for O2=32/4=8

Answer 2

Concept:

• Equivalent mass
• The mass of one equivalent, or the mass of a given material that will combine with or replace a specified amount of another substance, is known as equivalent weight in chemistry.
• Equivalent mass of metal/equivalent mass of oxygen = mass of metal/mass of oxygen

Given:

• Equivalent mass of oxygen = 8 g
• Mass of metal = 32 g
• Mass of oxygen = 48 g

Find:

• The equivalent mass of metal

Solution:

• Equivalent mass of oxygen = 8 g
• Equivalent mass of metal/equivalent mass of oxygen = mass of metal/mass of oxygen
• E/8 = 32/48
• E/8 = 2/3
• E = 16/3
• The equivalent mass of metal is 16/3 g

16/3 g is the equivalent mass of the metal.
