<u>Answer:</u> The mass percent of water in the hydrated salt is 43.6 %
<u>Explanation:</u>
To calculate the mass for given number of moles, we use the equation:
Moles of water = 8 moles
Molar mass of water = 18 g/mol
Putting values in above equation, we get:
We are given:
Mass of anhydrous salt = 186.181 g
To calculate the mass percentage of water in the hydrated salt, we use the equation:
Mass of hydrated salt = [186.181 + 144]g = 330.181g
Mass of water = 144 g
Putting values in above equation, we get:
Hence, the mass percent of water in the hydrated salt is 43.6 %
Answer: 292.81
Get Kelvin by adding 273 to the Celsius You set it up with 7.82/355K • 6.45/X
Cross multiply 7.82•X and 6.45•355
You get 7.82X=2289.75
Divide both sides by 7.82 to get x=292.81
