How many moles of Lithium Fluoride will you need to add to 250.0 mL of water to make a 5.00 M solution?
Alex17521 [72]

Answer:

1.25 mol LiF

Explanation:

5.00 M solution means

5.00 mol LiF in 1 L solution=1000mL

x mol LiF        in                        250 mL

x = 5.00*250/1000 = 1.25 mol LiF

If you want to prepare 2.00 L of a 0.800 M NaNO_3 solution from a NaNO_3 stock solution that is 1.5 M in concentration, how many
Leya [2.2K]

1066.7 ml of the stock solution must start with, preparing 2.00 L of a 0.800 M NaNO3 solution.

<h3>What is volume?</h3>

Volume is the space occupied by a three-dimensional object.

By the formula \rm M_1V_1= M_2V_2

M1 is the initial molarity, 1.5 M

M2 is the final molarity, 0.800 M

V1 is the initial volume

V2 is the final volume, 2.00 L

Putting the values in the equation

\rm 1.5\;M \times V_1= 0.800\;M \times 2.00\;L\\\\V_1 = \dfrac{ 0.800\;M \times 2.00\;L}{1.5\;M} = 1066.7\;ml

Thus, the initial volume is 1066.7 ml
