Question

If 2.1 moles of CaCl2 are dissolved in enough water to make a 0.92-liter solution, what is the resulting molarity?
Answer







2.3 M CaCl2
0.44 M CaCl2
0.70 M CaCl2
3.0 M CaCl2

Answer 1

concentration is the ratio of moles of solute per liter of solution:
\[M = \frac{mol\space solute}{L\space solution}\]
plug and solve

Answer 2

2.3?

Answer 3

2.3M
