The simplest formula of a compound containing 50 % of element x(Z=10)&...
Let the mass of compound be 100 g then mass of element x = 50 g and mass of element y = 50 g...no.of moles of x= 50÷10 = 5no.of moles of y= 50÷20 = 2.5now by dividing both no.of moles by the smallest of them...we get the ratio 2:1 .Hence the formula of the compound is X2Y

The simplest formula of a compound containing 50 % of element x(Z=10)&...
Understanding the Elements
- Element X (Z=10): This element has an atomic number of 10, which corresponds to Neon (Ne).
- Element Y (Z=20): This element has an atomic number of 20, corresponding to Calcium (Ca).
Percentage Composition
- The compound in question consists of 50% of Element X and 50% of Element Y.
- This equal distribution indicates that the molar ratios are the same.
Calculating Molar Mass
- Molar mass of Element X (Ne) = 20.18 g/mol.
- Molar mass of Element Y (Ca) = 40.08 g/mol.
Determining the Simplest Ratio
- Given the 50% composition, we can assume 100 grams of the compound. This leads to:
- 50 grams of Element X (Ne)
- 50 grams of Element Y (Ca)
Conversion to Moles
- Moles of Ne = 50 g / 20.18 g/mol ≈ 2.48 moles
- Moles of Ca = 50 g / 40.08 g/mol ≈ 1.25 moles
Finding the Simplest Whole Number Ratio
- To simplify the ratio, divide both by the smallest number of moles:
- Ne: 2.48 / 1.25 ≈ 1.984 (approximately 2)
- Ca: 1.25 / 1.25 = 1
Final Formula
- The simplest formula of the compound is represented as Ne2Ca, indicating that for every two atoms of Neon, there is one atom of Calcium.
This compound showcases the balance between these two distinct elements based on their proportions and molar masses.
- Element X (Z=10): This element has an atomic number of 10, which corresponds to Neon (Ne).
- Element Y (Z=20): This element has an atomic number of 20, corresponding to Calcium (Ca).
