What is the volume of 0.200 mol of an ideal gas at 200. kPa and 400. K?
gregori [183]

The ideal gas under STP is 22.4 L/mol. While the gas has a rule of P1V1/T1=P2V2/T2. So the volume under 101 kPa and 273 K is 0.2*22.4=4.48 L.

How many grams does f Cacl2 should be dissolved in 750.0 mL of water to make a 0.100 M solution Cacl2
AVprozaik [17]

Answer:

8.324 g

Explanation:

First we <u>convert 750.0 mL into L</u>:

  • 750.0 mL / 1000 = 0.750 L

Then we <u>calculate the required number of moles of CaCl₂</u>, using the <em>definition of molarity</em>:

  • Molarity = moles / liters
  • Molarity * liters = moles
  • 0.100 M * 0.750 L = 0.075 mol

Finally we <u>convert 0.075 moles of CaCl₂ into grams</u>, using its <em>molar mass</em>:

  • 0.075 mol * 110.98 g/mol = 8.324 g
