A student needs to make 0.855 L of a sodium bromide solution for an experiment. The concentration of the required solution is 0.

d1i1m1o1n [39]

Answer:

Explanation:

Molarity = moles/liters of solution

moles = molarity x Liters of solution

= 0.350 m/L x 0.855 L

= 0.299 mol

mass = moles x molar mass

= 0.299 mol x 102.89 g/ms

= 30.78 grams

The end point of a titration was reached after 22 ml of 0.050 m disodium edta titrant was dispensed into a solution containing t

ale4655 [162]

The moles of disodium edta used is calculated using the below formula

moles =molarity x volume in liters

molarity=0.050m
volume in liters = 22/1000=0.022 L

moles is therefore= 0.022 x0.050 =1.1 x10^-3 moles of disodium edta
