1. 0.0014 mol
Answer 1
you have 40.0 ml and you have a molarity of 0.035 M, so you can use the molarity formula to calculate the moles. First you need to convert 40.0 mL to L:
40.0mL (1L/1000mL) = 0.040L
then put in the formula M = moles/liters
0.035 M = moles / 0.040 L
multiply both sides by 0.040L, and you get 0.0014 moles
so the answer is 1

answer 2
0.035 mole in 1000 ml
x mol in 40 ml
(0.035 x 40) / 1000 = 0.0014 mol
Not. 1 is the answer.
