Zinc (Zn) is a silvery metal that is used in making brass (with copper) and in plating
iron to prevent comosion How many moles of Zn are there in 23.3 g of Zn?
Strategy We are trying to solve for moles of Zn. What conversion factor do we need
to convert between grams and moles? Arrange the appropriate conversion factor so that
grams cancel and the unit mol is obtained for your answer.
Solution The conversion factor needed to convert between grams and moles is the
molar mass. In the periodic table (see inside front cover) we see that the molar mass
of Zn is 65.39 g. This can be expressed as
1 mol Zn=65.39 g Zn
From this equality, we can write the two conversion factors
1 mol Zn
65.39 g Zn
and
65.39 g Zn
1 mol Zn
The conversion factor on the left is the corect one. Grams will cancel, leaving unit of
mol for the answer. The number of moles of Zn is
1 mol Zn
23.3 gZí x 65 30 0356 mol Zn
Thus, there is 0.356 mole of Zn in 233 g of Zn
Check Because 23.3 g is less than the molar mass of Zn, we expect the result to be
less than 1 mole.


PART 1:Create a program that would
replicate the following problem. (30 pts)

PART 2: From the above problem, create
a program that would ask the user for
the number of grams of an element and
compute for the nunmber of moles. (20
pts)


CAN ANYONE HELP ME PLS......GUIDE ONLY

Hello anong guide ba yung need mo ? kase may instruction na jan sa post mo nanjan na din formula itatype mo nalang .

 

[Llewor1]

Gagawa ka yata ng same scenario tulad ng nasa taas ng part 1 tol using different variables?

Corrosion din yata yun instead of comosion..

PART 1:Create a program that would
replicate the following problem. (30 pts)

Palagay ko gagawa ka d2 ng problem tulad ng sample mo sa taas since may term na replicate(gagayahin or to reproduce but using different variables or mixture of elements)

PART 2: From the above problem, create
a program that would ask the user for
the number of grams of an element and
compute for the nunmber of moles. (20
pts)

Dito palagay ko yung answer or the solution sa problem na ginawa mo sa part 1..

Not sure pero baka lang naman..

tama silang dalawa. although naguluhan ako sa "program" na term but anyway just find an element sa periodic table. kung tama pagkakaintindi ko sa "program" magcreate ka ng problem and solution as well gaya ng example. The question is limited lang ba sa metal ang topic niyo? anyway for example Fe ang napili kong element, gaya sa sample gawan mo na din ng description and utility. then jump to the question which is about how many moles sa grams(na crineate mong problem). of you have to provide how many grams ang 1 mole nung element. so gayahin mo lang yung sample.
PAra naman sa part 2. it's the reverse "program" naman. which means mass to moles lang. but since sinabing mag aask pa ng lang grams yung element ang sinasabi lang (sa pagkakaintindi ko) is you have to give the conversion 1 mole of element to grams as a given data lang din. basta isipin mo na lang gumagawa ka ng quizkung teacher ka. para ka kasing pinapagawa ng problem solving e .hope nakatulong char
