Answer:
37.5 g NaCl
Explanation:
Step 1: Given data
- Concentration of NaCl: 15.0% m/m
- Mass of the solution: 250.0 g
Step 2: Calculate how many grams of NaCl are in 250.0 g of solution
The concentration of NaCl is 15.0% by mass, that is, there are 15.0 g of NaCl every 100 g of solution.
250.0 g Solution × 15.0 g NaCl/100 g Solution = 37.5 g NaCl
Answer:
Here's what I get
Explanation:
I think this may be the equation you intended to write:
C₃H₅(OH)₃ + 3HCl ⟶ C₃H₅Cl₃ + 3H₂O
The mole ratios are the ratios of the coefficients in the balanced equation.
Here are some of the possible molar ratios.
- C₃H₅(OH)₃:HCl = 1:3
- C₃H₅(OH)₃:C₃H₅Cl₃ = 1:1
- C₃H₅(OH)₃:H₂O = 1:3
- HCl:C₃H₅Cl₃ = 3:1
- HCl:H₂O = 3:3
- C₃H₅Cl₃:H₂O = 1:3
I believe Fission i'm not 100% sure though
The answer is Silver (Ag)
You can use the formula: C = k - 273 to solve this problem. C stands for Celsius, and k stands for kelvin. Given the information that the Kelvin is 172k, then you can plug it into the equation and get C = (172) - 273. The correct melting point in C is -101°C. Hope this helped!
