I have this project on a compound of our choice and I chose TNT.
I have 2/3's of the project done, but the calculations part is stumping me something serious
If you could help me out, or explain to me how to do this that would me amazing


1.)Calculate how many moles of TNT you have if you have 5g, 75g, 300g, 1000g, and 1.5kg of TNT. Show all formulas, conversions and calculations


2.)Calculate how many molecules of TNT you have if you have 5g, 75g, 300g, 1000g, and 1.5kg of TNT.
Show all formulas and calculations with correct units, and put your answers in scientific notation

3.)Calculate how to make these molar solutions:
1. 1M, 1L solution
2. 0.1M, 5L solution
3. 3M, 250ml solution
4. 18M, 1500mL solution
5. 0.05M, 25mL solution

i have 0 idea how to do this

You have to show your attempts at solving the question to receive help. This is a forum policy.

At least list related definitions and formulas.

If you want to determine how many moles are in a sample of TNT, you must first determine its molar mass. C7H5N3O6 is its chemical formula. Just take the AMUs of all the elements involved, add them together, and you will have the amount of grams that make up one mole of TNT. You can then divide your various mass amounts by this number.

Finding the molar mass is the first step you need to take, and from there you can effectively determine the answers to all of your questions. Best of luck on your project.
