Answer:
16.06 L was the initial volume of the balloon.
Explanation:
Initial moles of freon in ballon =
Initial volume of freon gas in ballon =
Moles of freon gas added in the balloon = n = 3.50 mole
Final moles of freon in ballon =
Final volume of freon gas in ballon =
Using Avogadro's law:
( at constant pressure and temperature)
16.06 L was the initial volume of the balloon.
True, in space the tail of a comet will be cold since it a. doesnt have a hot core and b. are typically not found near the sun
Answer:
1.30464 grams of glucose was present in 100.0 mL of final solution.
Explanation:
Moles of glucose =
Volume of the solution = 100 mL = 0.1 L (1 mL = 0.001 L)
Molarity of the solution =
A 30.0 mL sample of above glucose solution was diluted to 0.500 L:
Molarity of the solution before dilution =
Volume of the solution taken =
Molarity of the solution after dilution =
Volume of the solution after dilution=
Mass glucose are in 100.0 mL of the 0.07248 mol/L glucose solution:
Volume of solution = 100.0 mL = 0.1 L
Moles of glucose =
Mass of 0.007248 moles of glucose :
0.007248 mol × 180 g/mol = 1.30464 grams
1.30464 grams of glucose was present in 100.0 mL of final solution.
