Question

11. An oxide of manganese was found to contain 69.64% manganese. What is the simplest
formula of the oxide????

PLEASE Guys solve It With Full Process..​

Answer 1

Since % is given let's take a 100g sample

Therefore, mass of manganese in the sample is 69.64g

And mass of oxygen in the sample is 30.36g

Element -Mn

• Mass - 69.64g
• No of mole - 1.26
• Mole ratio- 1

Element- O

• Mass - 30.36
• No of Mole - 1.89
• Mole ratio - 1.5

From above data we get Mole ratio in whole numbers that is Mn - 2 (1+1) and O - 3 (1.5+1.5)

Therefore Formula of the given Manganese oxide is Mn2O3
