[Mr.Konami]

Hello .

I am french educated , and now we're studying chemistry lab in english    everything is easy but to understand the technical word in english is a bit hard . but the teacher is cute and pretty so i Like the Lab class 

anyway she told us to resolve and make a report ;

1- weigh : 0.585 g of Nacl
2.transferit to a volumetric flask using a tunnel
3-add a  small amount of H2O to dissolve Nacl , then fill it to the mark .
4-calculate the matority of the solution
5-using solution A , prepare 50 ml of 0.1M / 0.05M/ 0.01M Nacl

i solved them All c1v1 =c2v2 -> so c2 = 0.1L
5- for 0.1M we got : 25ml
for 0.05 we got : 12.5ml
for 0.01M we got: 2.5Ml

everything is easy for now  we used to do it in our french program but now i have a big problem she told us to make a report ; i am new and its very hard to do a reports coz i have never saw a reports before .

Report:
1-title :
2.objectif
3.introduction
4.theory
5.procedure
6.given data
7.calculations
8.comments and source of errors

I tried to solve them but i don;t know the name of this reaction in English or anything please could you help me ? i don't want her to be angry coz she's a good teacher .

Thank you
