M8 Review: Solutions (Chem)

Front

What is molarity?

Back

Molarity (M) is a measure of concentration defined as the number of moles of solute per liter of solution.

Front

How do you calculate molarity?

Back

Molarity (M) = moles of solute / liters of solution.

Front

What is the molar mass of sucrose (C12H22O11)?

Back

The molar mass of sucrose is 342 g/mol.

Front

What is the pH scale range?

Back

The pH scale ranges from 0 to 14.

Front

What does a pH of 7 indicate?

Back

A pH of 7 indicates a neutral solution.

Front

What is a base in terms of ion release?

Back

A base is a substance that releases OH- ions when dissolved in water.

Front

What is the formula to calculate the number of moles?

Back

n = MV, where n is the number of moles, M is molarity, and V is volume in liters.

Front

How many moles are in 1.7 L of a 0.35 M solution?

Back

0.595 mol.

Front

What is the relationship between moles, molarity, and volume?

Back

The number of moles is directly proportional to both molarity and volume.

Front

What is the significance of a solution's molarity?

Back

Molarity indicates the concentration of a solute in a solution, affecting reaction rates and properties.
