Molar concentration is the amount of solute in moles divided by 1 liter of solvent. Then to answer this question, you need to convert the 23g of ammonium chloride into mole unit. Since the mass of nitrogen = 14, helium =1, and chlor= 35.453 then the molecular mass of (NH4)Cl should be: 14+4+35.453= 53.5
Then, the molarity should be: 23g/ (53.5gr/mole)/ (500ml/1000ml)= 0.86molality
Chemists use reactions to generate a desired product. For the most part, a reaction is only useful if it occurs at a reasonable rate. For example, a reaction that took 8,000 years to complete would not be a desirable way to produce brake fluid. However, a reaction that proceeded so quickly that it caused an explosion would also not be useful (unless the explosion was the desired result). For these reasons, chemists wish to be able to control reaction rates. In order to gain this control, we must first know what factors affect the rate of a reaction. We will discuss some of these factors in this section.
No :) They see different parts but I am a little confuse when you say the same part ;P
Answer:
D. 613
Explanation:
I just had to answer it and that was the correct answer :)
(i didn't know it either so i was looking for help and then i came across someone who was struggling too so-)
_Award brainliest if helped!
Assume Specific Heat capacity of water = 4.186 J/g<span>°C
100g sample,
