Mylanta is composed of aluminum hydroxide and calcium carbonate. assuming that a mylanta tablet contains 175 mg of aluminum hydroxide and 145 mg of cakcium carbonate, answer the following:

how many mL of 0.00836 M HCL (aq) can be neutralized with 2 Mylanta tablets.

I balanced the equation and multiplied the tablets by 2 to get 290 mg of CaCo3 and 350 mg Al(OH)3.

The I divided 290 by 200.02 g (is this the correct molecular weight of calcium carbonate. and multiplied this number by the mole ration of 2 moles HCl to 1 mole calcium carbonate to get 0.006 moles HCl, but now i'm unsure of what to do next?
