Answer:
.224 M
Explanation:
To begin, we need to find the molar mass of Na2S
To find Molarity, we use the equation M=moles/Liters of solution
We are given grams, so we must divide by the molar mass of Na2S to find moles.
- 8.76g Na2S / 78.05g/mol Na2S= .112 moles
Now we use our Molarity equation:
- .112 moles Na2S / .500L of solution = .224 M
The formula is density = mass / Volume
density = 1.7 g/mL
mass = 95 grams
Volume = ?
1.7 g/mL = 95 g / Volume
Volume = 95 g / 1.7 g/mL
Volume = 55.88 mL
Hope this help!
