If 4.50 g of (nh4)2so4 is dissolved in enough water to form 250. ml of solution, what is the molarity of the solution?
natima [27]
The molarity of a solution is the number of moles of a substance in one liter of that substance. 
The molar mass of ammonium sulfate (NH4)2SO4 is 132.14 grams/mole
Calculate the moles of ammonium sulfate:
(4.50 grams)/(132.14 grams/mole) = 0.0341 moles of ammonium sulfate
convert mL to Liters 250. mL becomes 0.250 liters
Take the number of moles over the number of liters
0.0341 moles / 0.250 liters = 0.136 molar or 0.136M = molarity of the solution

An unknown rectangular substance measures 3.60cm high, 4.21cm long, and 1.17cm wide. If the mass is 21.3g what is this substance
tino4ka555 [31]

The rectangular substance measures 3.60cm high, 4.21cm long, and 1.17cm wide. If the mass is 21.3g  substances density will be 1.20 centimeter cube.

<h3>What is density?</h3>

The density of any substance is the ratio of the mass of substance to the volume of the substance and the unit will be centimeter cube.

The volume of the substance will be 3.60cm high × 4.21cm long ×1.17cm wide = 17.7 milliliters.

                       density = mass of substance / volume of substance

Substituting the value in formula

                        Density = 21.3g /  17.7 milliliters.

                         Density =  1.20 centimeter cube.

Therefore,  rectangular substance measures 3.60cm high, 4.21cm long, and 1.17cm wide. If the mass is 21.3g  substances density will be 1.20 centimeter cube.

For the reaction NH4NO3 (s) → N2O (g) + 2H2O (l), you decompose 1 mole NH4NO3 and only get 0.75 moles of N2O. The percent yield
attashe74 [19]

Answer:

The answer to your question is False.

Explanation:

Data

1 mole of NH₄NO₃

0.75 moles of N₂O

Percent yield = 25%

Chemical reaction

               NH₄NO₃   ⇒   N₂O  +  2H₂O

Process

1.- Determine the theoretical yield

              1 mol NH₄NO₃ ------------- 1 mol of N₂O

2.- Calculate the percent yield

             Percent yield = Actual yield / Theoretical yield  x 100

-Substitution

              Percent yield = 0.75 / 1 x 100

-Simplification

              Percent yield = 0.75 x 100

-Result

              Percent yield = 75%

Conclusion

False, the actual percent yield is 75%
