question 3 (2 points)\nwhat is the % cl in the compound c₅h₁₀ocl₂?\n45.14 % cl\n22.57 % cl\n38.24 %…

Explanation:

Step1: Calculate molar mass of each element in the compound

The molar mass of C is 12.01 g/mol, H is 1.01 g/mol, O is 16.00 g/mol, and Cl is 35.45 g/mol. For (C_5H_{10}OCl_2), the molar - mass of carbon in the compound is (5\times12.01 = 60.05) g/mol, hydrogen is (10\times1.01=10.10) g/mol, oxygen is 16.00 g/mol, and chlorine is (2\times35.45 = 70.90) g/mol.

Step2: Calculate the molar mass of the compound

The molar mass of (C_5H_{10}OCl_2) is (M = 60.05+10.10 + 16.00+70.90=157.05) g/mol.

Step3: Calculate the percentage of Cl

The percentage of Cl in the compound is (\text{Percent of Cl}=\frac{\text{Mass of Cl in compound}}{\text{Molar mass of compound}}\times100%=\frac{70.90}{157.05}\times100%\approx45.14%)

Answer:

45.14 % Cl
