Answer:
The molar mass of any substance is the mass in grams of one mole of representative particles of that substance. ... In such a conversion, we use the molar mass of a substance as a conversion factor to convert mole units into mass units (or, conversely, mass units into mole units).
Explanation:
I think it is D but im not sure
Answer:
0.00688 moles
Explanation:
The molarity ratio looks like this:
Molarity = moles / volume (L)
After you convert mL to L, you can plug the values into the equation and simplify to find moles.
27.5 mL / 1,000 = 0.0275 L
Molarity = moles / volume <----- Molarity ratio
0.250 M = moles / 0.0275 L <----- Insert values
0.00688 = moles <----- Multiply both sides by 0.0275
