The given compound HS1U1B13S1U1B0OS1U1P1+S1S1P0 can be simplified to H2S2O3. The concentration can be calculated using the equation:
[Moles of solute]/[Volume of solution in liters]
To find moles of solute, we need to know the molar ratio between HCl and H2S2O3. From the balanced chemical equation:
H2S2O3 + 2HCl → 2S1U1B0OS1U1P1 + 2S1S1P0 + 2H2O
we can see that 1 mole of H2S2O3 reacts with 2 moles of HCl. Therefore, the moles of H2S2O3 in 0.0010 M HCl are:
(0.0010 M HCl) x (2 moles H2S2O3 / 2 moles HCl) = 0.0010 M H2S2O3
Now we can substitute into the equation:
[Moles of solute]/[Volume of solution in liters] = [0.0010 moles]/[1.00 L] = 0.0010 M
Converting to scientific notation gives:
0.0010 M = 1.0 x 10^-3 M
Finally, we convert to S1U1P1-3 S1S1P0M, giving the answer of B.
