What is the volume of a 4.0M solution that contains 374 grams of KNO3?

0.93L

Explanation:

The following data were obtained from the question:

Molarity = 4M

Mass of KNO3 = 374g

Volume =..?

We'll begin by calculating the number of mole in 374g of KNO3. This is illustrated below:

Mass of KNO3 = 374g

Molar mass of KNO3 = 39 + 14 + (16x3) = 101g

Number of mole of KNO3 =..?

Number of mole = Mass/Molar Mass

Number of mole of KNO3 = 374/101 = 3.70 moles.

Now, we can obtain the volume of the solution as follow:

Molarity = mole /Volume

Volume = mole /Molarity

Volume = 3.70/4

Volume = 0.93L

Therefore, the volume of the solution is 0.93L

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
