5 g of calcium combine with 2 g of oxygen to form a compound . find the molecjlar formula of the compound
Answers
Answer:
The answer will be 56.
Explanation:
Calcium and Oxygen combine to form Calcium Oxide.
2Ca + O2 → 2CaO
Therefore 5g of Calcium and 2g of Oxygen gives 7 g of Calcium Oxide.
The molecular formula of CaO will be = Molecular mass of Calcium + Molecular mass of Oxygen
= 40+16
= 56.

Explanation:
Explanation:Number of moles in 5g of calcium
Explanation:Number of moles in 5g of calciumMass/ molar mass = 5/40
Explanation:Number of moles in 5g of calciumMass/ molar mass = 5/40 = 0.125
Explanation:Number of moles in 5g of calciumMass/ molar mass = 5/40 = 0.125
Explanation:Number of moles in 5g of calciumMass/ molar mass = 5/40 = 0.125
Explanation:Number of moles in 5g of calciumMass/ molar mass = 5/40 = 0.125 Number of moles in 2g of oxygen
Explanation:Number of moles in 5g of calciumMass/ molar mass = 5/40 = 0.125 Number of moles in 2g of oxygenMass/ molar mass = 2/16
Explanation:Number of moles in 5g of calciumMass/ molar mass = 5/40 = 0.125 Number of moles in 2g of oxygenMass/ molar mass = 2/16 = 0.125
