    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.
