• # Need solutions to Mixed mole problems

Having a problem about mixed mole? Searching for solution? On this Ask Expert page check out resolution to all your queries.

Note: I need a complete solution:
1) How many grams are there in 3.33x10^25 molecules of sulfuric acid?
2) What volume would the sulfuric acid in problem 1 occupy at STP?
3) A sample of ammonium nitrate occupies 65.0 liters at STP. How many molecules is this?
4) What is the mass of the sample ammonium nitrate in Problem 3?
5) A 25.0g sample of acetic acid is in a container at STP. What volume is the container?
6) How many molecules of acetic acid are in the container in Problem 5?
7) How many grams are there in 2.35x10^26 molecules of aluminum acetate?
8) What volume would the aluminum acetate in Problem 7 occupy at STP?
9) A sample of sodium carbonate occupies 35.5 liters at STP. How many molecules is this?
10) What is the mass of the sample sodium carbonate in Problem 9?
11) A 85.0g sample of phosphoric acid is in a container at STP. What volume is the container?
12) How many molecules of phosphoric acid are in the container in Problem 11?
13) A 123g sample of iron (lll) sulfate is in a container at STP. What volume is the container?
14) How many molecules of iron (lll) sulfate are in the container in Problem 13?
Experts: do provide solution.
• You have asked many questions in one thread. However, see the first few answers found in other websites, as below;

1. moles of H2SO4 = > 3.33x10^25/6.023 x 10^23 = > 0.5 x 100 = 50 mass = 50 x 22.4 = > 1120 gms.

2. Volume at STP => 50/22.4 = > 2.228 litre.

3. Moles at stp => 65/22.4 = > 2.90 moles.
No. of molecules = 2.90 x 6.023 x 10^23 = 17.44 x 10^23.

4. mass of Aluminium nitrate = > 2.90 x 213 = 618 gm approx.

5. moles = 25/60 = > 0.416
Volume at STP = > 0.416 x 22.4 => 9.33 litres.

6. No. of molecules = > 0.416 x 10^23 x 6.023 = > 2.509 x 10^23.

Hope these helps.
