Determine the molarity of a solution formed by dissolving 4.00 moles of KBr in enough water to yield 3.00 L of solution.

1 answer:

3 0

Molarity (M) is the numer of moles per liter (mol/L)

Both are already given:
mol = 4.00 moles of KBr
L = 3.00 L H2O (water)

Plug them both into the equation:
4.00 mol KBr = 1.33 M KBr (1.33 because of sig figs)
3.00 L H2O

In the lab you find four bags; each contains 5.00 g of a different gas at STP. The gases are O2, CH4, CO2, and He. Which bag has

hichkok12 [17]

Answer:

lesser the molar mass of the gas higher the no. of moles included in a certain mass sample. ie at STP more volume is required for the gas having less molar mass.

He has the smallest molar mass.

Therefore bag of He is the biggest.
