Answer:
Empirical formula is CCl₄
Explanation:
Given data:
Percentage of carbon = 7.70%
Percentage of chlorine = 92.3%
Empirical formula = ?
Solution:
Number of gram atoms of Cl = 92.3 / 35.5 = 2.6
Number of gram atoms of C = 7.70 / 12 = 0.64
Atomic ratio:
C : Cl
0.64/0.64 : 2.6/0.64
1 : 4
C : Cl = 1 : 4
Empirical formula is CCl₄.
The product is 63.8564
The correct number of S.F is 64.0000
Answer:
0.024M
Explanation:
Data obtained from the question include:
C1 = 6M
V1 = 2mL
C2 =?
V2 = 500mL
The molarity of the diluted solution can be obtained as follows:
C1V1 = C2V2
6 x 2 = C2 x 500
Divide both side by 500
C2 = (6 x 2) /500
C2 = 0.024M
The molarity of the diluted solution is 0.024M
