Answer:
27.3 g HCl
Step-by-step explanation:
**Be sure to arrange the conversion in a way that allows for the cancellation of units.
(Step 1)
Convert milliliters (mL) to liters (L).
1,000 mL = 1 L
250 mL 1 L
--------------- x ----------------- = 0.25 L
1,000 mL
(Step 2)
Use the molarity ratio to find the moles of HCl.
Molarity = moles / L
3 M = moles / 0.25 L
0.75 = moles
(Step 3)
Convert moles to grams using the molar mass of HCl.
Molar Mass (HCl): 1.008 g/mol + 35.453 g/mol
Molar Mass (HCl): 36.461 g/mol
0.75 moles HCl 36.461 g
-------------------------- x -------------------- = 27.3 g HCl
1 mole
