# How many grams are in 1.50 moles of KMnO4?

A later schools question and answer asked students to declare what they ponder is the most crucial important element for a student to do in order to become success. Of the numerous reactions, one that that stood out was practice. People who usually are successful do not become successful by being born. They work hard and commitment their lives to succeeding. If you want to complete your goals, keep this in mind! as follows some question and answer examples that you can easily work with to supercharge your knowledge and gain insight that will help you to preserve your school studies.

## Question:

How many grams are in 1.50 moles of KMnO4?A. 165.06
B. 660.24
C. 178.41
D. 237.06
E. 484.29

There are 237.06 grams in 1.50 moles of KMnO4.

HOW TO CALCULATE MASS:

• The mass of a substance can be calculated by multiplying the number of moles in the substance by its molar mass. That is;
• mass of KMnO4 = no. of moles × molar mass of KMnO4
• Molar mass of KMnO4 = 39 + 55 + 16(4)

= 158g/mol

• mass of KMnO4 = 158g/mol × 1.5mol
• Mass of KMnO4 = 237g
• Therefore, there are 237.06 grams in 1.50 moles of KMnO4.

From the answer and question examples above, hopefully, they might be able to assist the student sort out the question they had been looking for and keep in mind of all things declared in the answer above. Then could actually carry out some sharing in a group discussion and also study with the classmate that is related to the topic, so another student also have some enlightenment and still keeps up the school learning.
