Just so you know, that initial concentration of HCl couldn't possibly be safe to use; it's about 10 times the concentration of the stock HCl that university labs let students use at all. But OK, let's see. I assume …

Does dilution change the concentration? A 3.0 L solution contains 73.5 g of #H_2SO_4#. What is the molar concentration of the solution? If 40.0 mL of a #3.0x10^ (-5)# solution is diluted to 100 mL, what …

Answer is b Because geometric sequence has the formula as a_n=a_0r^ (n-1) where a_0 is the first term and r is the ratio. In our case a_0=1 r is the ratio which can be obtained a_2/a_1=3 and in …
