Question

nitrosyl chloride (nocl) is a highly toxic, yellow - green gas that irritates the eyes, lungs, and skin. despite these health concerns, it is commonly used to create precursors for synthetic fibers. how many moles of nocl are in 8.8 grams of nocl? refer to a periodic table. write your answer to the correct number of significant figures. round if necessary.

Explanation:

Step1: Calculate molar - mass of NOCl

From the periodic table, the molar mass of N is approximately 14.01 g/mol, O is approximately 16.00 g/mol, and Cl is approximately 35.45 g/mol. The molar mass of NOCl ($M$) is $M=14.01 + 16.00+35.45=65.46$ g/mol.

Step2: Calculate moles of NOCl

The number of moles ($n$) is calculated using the formula $n=\frac{m}{M}$, where $m = 8.8$ g and $M = 65.46$ g/mol. So $n=\frac{8.8}{65.46}\approx0.13$ mol.

Answer:

0.13
