First take all percents and make them grams. Since you're not given a overall molar mass you can assume it is 100 and therefore the percents are their masses. So you have 14.31g Carbon, 1.2g Hydrogen, and 84.49g of Chlorine. Next you divide each by their molar masses to get moles of each.
Next you divide each of those numbers by the smallest, in this case, Hydrogen. Thus, Carbon= <u>1.19moles</u> Hydrogen= <u>1.188moles</u> Chlorine= <u>2.411moles</u> 1.188moles 1.188moles 1.188moles =1.002 =1 =2.02 These are all close enough to round, so your final empirical formula is: CHCl2 Hope that helps!!
There are multiple ways to prevent these situations from occurring. The three most common protective devices are fuses, circuit breakers, and surge protectors
A_____PENCIL______ consists of a mixture of graphite powder (a form of carbon) and clay that is baked and hardened and encased in wood or paper. a. silverpoint b. pencil c. charcoal d. chalk e. paste
Explanation:
A pencil is a writing material, where the graphite is what gives the black color to the writing stroke.
