Answer:
2.23M
Explanation:
Molarity of a solution is calculated thus
Molarity = number of moles (n) ÷ volume (V)
According to this question, 4.11g of Zn metal was used in order to reach a volume of EDTA solution of 28.26 mL.
28.26mL = 28.26/1000
= 0.02826L
Using mole = mass/molar mass to calculate no. of moles of Zn
Mole = 4.11/65.4
mole = 0.0628mol
Molarity = 0.0628 ÷ 0.02826
Molarity = 2.23M
The concentration of the EDTA solution used is 2.23M
Answer:
Density = Mass / Volume ..... which means that .....
Volume * Density = Mass
So....for the liquid in the bottle we have that
750 ml * 1.006 g / ml = Mass [ the "ml" cancels ]
750 * 1.006 g =
754.5 g .... this is the mass ["weight "] of the liquid .....
And the acetic acid is 4% of this
So........the mass ["weight"] of the acetic acid is 4% of this...so
.04 * 754.5 =
30.18 g
