A 0.50 M stock solution of sodium thiosulfate is used to prepare a dilute solution. If 250.0 mL
of the concentrated solution is diluted to a volume of 2.5 L, determine the molarity of the
new solution.
0 0.025M
O 0.10 M
O 0.050M
0 0.075M

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
