using the periodic table, find the molar mass of silicon tetrachloride (sicl₄). write your answer to the hundredths place. round if necessary. g/mol

Answer

Explanation:

Step1: Find molar mass of Si

From the periodic - table, the molar mass of silicon (Si) is approximately $28.09$ g/mol.

Step2: Find molar mass of Cl

From the periodic - table, the molar mass of chlorine (Cl) is approximately $35.45$ g/mol.

Step3: Calculate molar mass of $SiCl_4$

The formula for the molar mass of $SiCl_4$ is $M = M_{Si}+4\times M_{Cl}$. Substitute the values: $M = 28.09+4\times35.45$. First, calculate $4\times35.45 = 141.8$. Then, $M = 28.09 + 141.8=169.89$ g/mol.

Answer:

$169.89$ g/mol
