It is supposed to be mol/dm-3
Actually, 1 dm cube is the same as 1 litre.
Therefore, there is no need of conversion. Both are the same.

HCl + NaOH ― NaCl + H2O nNaOH = c*v = 0.01470 * 23.74*10-3L = 3.49*10-4 mol 1 mol HCl reacts with 1 mol NaOH therefore nHCl = 3.49*10-4mol CHCL= nNaOH /VNaOH = 3.49*10-4 / 25.00*10-3 = 13.96 * 10-3 mol.dm-3

To calculate the pH of a 0.001 mol/dm³ HCl solution, you use the formula pH = -log[H+]. For HCl, since it is a strong acid, it dissociates completely into H⁺ ions. Thus, the concentration of H⁺ ions in a 0.001 mol/dm³ HCl solution is also 0.001 mol/dm³. Taking the negative logarithm of 0.001 gives a pH of 3.
10 cm in 1 dm.. then just convert it.. for example: 70 cm = 1dm/10cm = 7 dm... what i did there was 70 x 1 / 10 = 7 dm
6.17 x 10-3 mol dm-3
To neutralize the Ba(OH)2, we need an equal number of moles of HCl. The molarity of Ba(OH)2 is 0.200 mol/dm^3, so the number of moles present in 25.0 cm^3 is (0.200 mol/dm^3) x (25.0 cm^3 / 1000 cm^3) = 0.005 mol. Since HCl and Ba(OH)2 neutralize each other in a 1:1 ratio, we need the same number of moles of HCl. Therefore, the volume of 0.200 mol/dm^3 HCl needed is (0.005 mol) / (0.200 mol/dm^3) = 0.025 dm^3, which is equivalent to 25.0 cm^3.
10 dm = 1 m Therefore 5600 dm = 560 m
To convert mm^3 to dm^3, you need to divide by 1,000,000 (since 1 mm^3 is equal to 1/1,000,000 dm^3). Therefore, to convert 16.74 mm^3 to dm^3, you would divide by 1,000,000 to get 0.00001674 dm^3.
You divide by 10.
To convert 0.9 dm to mm, you would multiply by 100 because there are 10 mm in 1 dm. Therefore, 0.9 dm is equal to 90 mm.
