CHEMISTRY
WHAT VOLUME OF O.4MOLE SODIUM CHLORIDE WILL CONTAIN O.585g OF NaCL? Solve and tell me d answer

calculate d oxidation number of nitrogen in NO3-

physics
what is d unit for luminions intensity called?

CHEMISTRY
1) 1MOLE of NACL gives 58.5g of NaCl, therefore, 0.4MOLE of NaCl will give: 0.4 × 58.5 = 23.4g.
58.5g of NaCl is equal to 22.4dm3, therefore, 23.4g of NaCl will give: 23.4 × 22.4 ÷ 58.5 = 8.96dm3. Since 58.5 ÷ 100 = 0.585, therefore 8.96 ÷ 100 = 0.0896dm3 or 89.6cm3.

2) N + (-2 × 3) = -1
N + (-6) = -1
N - 6 = -1
N = -1 + 6
N = +5.
Note: N stands for nitrogen.

Hydroscopic means ability to attract and hold water from the environment

How come? @the bolded. NaCl is not a gas na. The molar volume off every gas is 22.4dm3 but not NaCl. I stand to be corrected though

Thank you all for doing a wonderful job here God bless you

The question itself says how many volume of 0.4mole of NaCl can be found in 0.585g of NaCl. Does the question also treat it as gas?
Back to my own analysis; 1mole = 58.5g = 22.4dm3 of NaCl.

Halpher: Carbon(iv)oxide has how many lone and unpair electron?

Lone pair is the same as unpaired electron in a chemical bond.

You know I could as well say that 1mol = 58.5g= 27cm3 and I would also be correct? Since NaCl is not a gas, we can't assume that it's molar volume is 22.4dm3 The question itself is illogical to some extent I think.

Halpher:
Did I told you I don't understand that?? Propably NO sire. Funny dudes.

Should be "Did I tell you" instead of "Did I told you"

It wouldn't be fair if I continued to overlook this error, although it may seem that I'm overreacting, but like I said earlier in this thread, we learn everyday and no-one is perfect. I only hope you don't take it offensively

morning everybody how are u all

Am happy you understood the approach I used to answer the question. I also thought about it that NaCl isn't a gas how come should will be asked to calculate it's volume even when it's density is not given, we are given only mole which implies that we have to make connection with Molar Volume which work with gases. But I felt my knowledge may be limited about the gaseous state of NaCl (which I have not come across) so I decided to apply my knowledge in solving problems like that to it.
If our assumption about the state of NaCl can't be treated as a gas is correct, then I totally agree with you that the question is illogical, and am the one who had make a mistake for attempting such an illogical question.
I appreciate your good work Mr Benjamin, but you need to come and clarify yourself of this question you posted.

Are you sure this thread is for UTME candidates? Most of the questions you guys are posting are beyond the scope of UTME and I don't think that will help the prospective candidates. I'll suggest/advice that questions should be based only on syllabus.#mythoughts

Hmmm..
Not at all Sire

Yea correct
