Answer:
The answer to your question is 0.57 moles
Explanation:
Data
volume = 1.9 L
[NaCl] = 0.3
moles of NaCl = ?
Process
1.- To solve this problem use the formula of Molarity.
Molarity = moles/ volume (l)
-Solve for moles
moles = Molarity x volume
-Substitution
moles = 0.3 x 1.9
-Result
moles = 0.57
-Conclusion
There are 0.57 moles of NaCl in 1.90 L of a 0.3 M solution.
