Answer to What is written under the periodic table.
Sorry I made a mistake
Mg = 24.31 Chlorine isn't shown but it should be 35.45 so 2 chlorines are
2Cl = 70.9
Total 95.21 I said 166 and that is not even close. Sorry.
570 mL = 580 mL * 1 L / 1000 mL = 0.570 L
n = V * Molarity. The molarity is given as 2
n = 0.57 * 2 = 1.14 moles
needed mass = moles * molar mass
moles = 1.14
molar mass = 95.21
needed mass = 1.14 * 95.21 = 108.5. Check my number for chorine.

The number of moles of chemical does not change.
n = Concentration * Volume
Starting volume = 1.24 L
Starting concentration = 2.13 Moles / L
Ending Concentration = 1.6 moles / L
1.24 * 2.13 = V * 1.6
V = 1.24 * 2.13/1.6
V = 1.65 L

Done. See first answer. Be sure and check the chlorine.
