Please I want the full calculation
To calculate the percentage by mass of silicon tetrachloride, you need to know the molar mass of silicon tetrachloride and the mass of the compound in question.
Silicon tetrachloride is composed of one silicon atom (Si) and four chlorine atoms (Cl). The molar mass of silicon is approximately 28.09 g/mol, and the molar mass of chlorine is approximately 35.45 g/mol.
1. Determine the molar mass of silicon tetrachloride by summing the molar masses of its constituent elements:
Molar mass of silicon tetrachloride = (1 × molar mass of silicon) + (4 × molar mass of chlorine)
Molar mass of silicon tetrachloride = (1 × 28.09 g/mol) + (4 × 35.45 g/mol)
Molar mass of silicon tetrachloride = 169.89 g/mol
2. Measure the mass of the silicon tetrachloride compound. Let's assume the mass is 50 grams.
3. Calculate the percentage by mass using the following formula:
Percentage by mass = (mass of silicon tetrachloride / total mass) × 100%
Percentage by mass = (50 g / 50 g) × 100%
Percentage by mass = 100%
Therefore, the percentage by mass of silicon tetrachloride in a sample weighing 50 grams is 100%.
It's 100% SiCl4
Was there something more specific you wanted?
Maybe something involving the molar mass of 169.9g
separated by element?
