How many moles of barium chloride are present in 6.5l of a 3m solution

Chemistry
1 answer:
Contact [7]3 years ago
8 0

Answer:

The answer to your question is 19.5 moles

Explanation:

Data

moles = ?

Volume = 6.5 l

Molarity = 3 M

Molarity is a unit of concentration that relates the number of moles by the volume (liters).

Formula

Molarity = moles / Volume

-Solve for moles

moles = Molarity x Volume

-Substitution

moles = 3 x 6.5

-Result

moles = 19.5

Aldehydes are usually more reactive<span> toward nucleophilic substitutions </span>than<span> ketones because of both steric and electronic effects. In aldehydes, the relatively small hydrogen atom is attached to one side of the carbonyl group, while a larger R group is affixed to the other side.</span>

Which has a larger molar mass, salt (NaCl) or sugar (C12H22011) – how can you tell?
uysha [10]

Answer:

Explanation:

Molar mass of NaCl = (23+35.5)

Molar mass of NaCl = 58.5g/mol

Molar mass of C12H22011

= 12(12) + 22(1) + 16(11)

= 144 +22 + 176

= 342g/mol

Please help me and explanation would be really awesome thank you!
valentina_108 [34]

Answer:

So the answer would be 10 moles

Explanation:

1) Start with the molecular formula for water: H_{2} O!

2) If there are 10 moles of water use a mole ratio to calculate the moles of oxygen it would produce.

(This question is... interesting... since they chose an element that is diatomic in free state so It could TECHNICALLY be two answers, moles of O or moles of O_{2})

The mole ratio is 1 moles of H_{2}O to 1 moles of O. This is because the coefficient for oxygen in water is simple 1, so the ratio is 1:1.

3) that means if 10 moles of water decompose, they decompose into 10 moles of H_{2} and 10 moles of O.

Extra:

About what I was saying before about the question being slightly interesting:

10 moles of pure oxygen is produced but free state oxygen exists as O_{2} so it could possibly be 10 OR 5! However, notice it says elements. This leads me to believe the answer is 10 (monatomic oxygen) instead of 5 (free state/diatomic oxygen).

I hope this helps!
