Question

using the periodic table, find the molar mass of trichlorofluoromethane (ccl₃f). write your answer to the hundredths place. round if necessary. g/mol

Explanation:

Step1: Identify atomic masses

From periodic table, $C = 12.01\ g/mol$, $Cl=35.45\ g/mol$, $F = 19.00\ g/mol$.

Step2: Calculate molar mass of $CCl_3F$

$M = 1\times12.01+3\times35.45 + 1\times19.00$
$M=12.01 + 106.35+19.00$
$M = 137.36\ g/mol$

Answer:

$137.36$
