How many moles of KCL are contained in 114 mL of a 1.85 M KCL solution?
4 answers
moles = M x L
so 114 ml is 0.114 L
1.85x 0.114 = 0.2109
??
1.85x 0.114 = 0.2109
??
please
Yes, my calculator reads 0.2109 g also, but I would round to 0.211 grams because you are allowed only 3 significant figures (comes from the 114 and 1.85, both 3 s.f. in those digits).
