How many moles are in 1.50 g of ethylamine, ch3ch2nh2?
2 answers:
Mass = mass/molar mass of ch3ch2nh2 the molar mass of CH3CH2NH2 = 12 +(1x3)+12+(1 x2)+14+(1x2) =45 g/mol moles is therefore = 1.50g /45g/mol = 0.033 moles
Answer: 0.03 moles
Explanation:
To calculate the moles, we use the equation:
....(1)
For ethyl amine
Mass of ethyl amine = 1.50 g
Molar mass of ethyl amine = 45 g/mol
Putting values in above equation, we get:

it would need to gain 2 more for it to achieve a stable configuration
the best way to remember this is the noble gasses all have 8 valence electrons and that they are the most stable elements on the periodic table

Answer:
Explanation:
You have an acid that is acidic or a base that is basic. When you mix the two, they form water (assuming those are bronsted-lowry acids and bases) which is neutral.
