Answer:

The solution contains 335.5 grams of KCl

Explanation:

Step 1: Data given

Volume of the KCl solution = 3.00 L

Molarity of the KCl solution = 1.50 M

Molar mass of KCl = 74.55 g/mol

Step 2: Calculate moles KCl

Moles KCl = molarity KCl solution * volume KCl solution

Moles KCl = 1.50 M * 3.00 L

Moles KCl = 4.50 moles

Step 3: Calculate mass of KCl

Mass KCl = moles KCl * molar mass KCl

Mass KCl = 4.50 moles * 74 .55 g/mol

Mass KCl = 335.5 grams

The solution contains 335.5 grams of KCl

Calculate the energy required to melt 21 g of ice at 0 oC.
vladimir1956 [14]

<u>We are given:</u>

Mass of ice = 21 grams

The ice is already at 0°c, the temperature at which it melts to form water

Molar heat of fusion of Ice = 6.02 kJ/mol

<u>Finding the energy required:</u>

<u>Number of moles of Ice: </u>

Molar mass of water = 18 g/mol

Number of moles = given mass/ molar mass

Number of moles = 21 / 18 = 7/6 moles

<u>Energy required to melt the given amount of ice:</u>

Energy = number of moles * molar heat of fusion

Energy = (7/6) * (6.02)

Energy = 7.02 kJ OR 7020 joules
