Answer #1

Since the answer posted to question 7 is 0.9M

Before and after dilution, the number of moles will be remain

M1V1 = M2V2

M1 = initial molarity = 0.9M

V1 = initial volume = 10 mL

M2 = final molarity = M2 (unknown)

V2 = final volume = 50 mL

(0.9)(10) = M2(50)

M2 = 0.18M

Since the answer is given till 2 significant figures, hence the final answer will be 0.2M
