How many moles are in an 11mL solution of NaOh and KHP (C8H4O4)

1 answer:

6 0

Answer:

Calculate the molar concentration of the NaOH solution that you prepared Number of moles of KHP = Number of moles NaOH = 2.476 x 10 -3 moles Number of moles NaOH = Mb x Vb Mb = 2.476 x 10 -3 moles / 0.0250 L (equivalence point) = 0.0990 M 3

A container was found in the home of the victim that contained 130 g of ethylene glycol in 380 g of liquid. What was the percent

Kaylis [27]

Answer:

34.21%

Explanation:

Given parameters:

Mass of ethylene glycol in the container = 130g

Mass of the liquid in total = 380g

Unkown:

Percentage of ethylene glycol in the liquid =?

Solution

To find the percentage of the ethylene glycol in liquid, we use the expression below:

Percentage of ethylene glycol in liquid = $\frac{mass of ethylene glycol}{mass of liquid}$ x 100

Percentage of ethylene glycol = $\frac{130}{380}$ x 100

Percentage of ethylene glycol = 34.21%
