Answer 1

A)

volume , V = 3.2 L

use:

number of mol,

n = Molarity * Volume

= 0.105*3.2

= 0.336 mol

Answer: 0.34 mol

B)

volume , V = 0.972 L

use:

number of mol,

n = Molarity * Volume

= 2.58*0.972

= 2.508 mol

Answer: 2.51 mol

C)

volume , V = 24.5 mL

= 2.45*10^-2 L

use:

number of mol,

n = Molarity * Volume

= 0.558*2.45*10^-2

= 1.367*10^-2 mol

Answer: 1.37*10^-2 mol
