What is the
of a 750 milliliters solution containing 54.0 grams of KBr?

0.605 M

Explanation:

What is the molarity of a 750 milliliters solution containing 54.0 grams of KBr?

Step 1: Given data

Step 2: Calculate the moles corresponding to 54.0 g of KBr

The molar mass of KBr is 119.00 g/mol.

54.0 g × 1 mol/119.00 g = 0.454 mol

Step 3: Calculate the molarity of the solution

Molarity is equal to the moles of solute divided by the liters of solution.

M = 0.454 mol / 0.750 L = 0.605 M

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
