Answer:
2.562
Step-by-step explanation:
First we convert 127 g of H₂CO₃ to moles, using its molar mass:
- 127 g ÷ 62 g/mol = 2.05 mol H₂CO₃
Then we convert 800 mL to L:
Finally we can calculate the concentration of the solution as molarity:
- molarity = moles / liters
- molarity = 2.05 mol / 0.800 L = 2.562 M
