Answer: 642.93 g of NaCl
Explanation:
11.00 mol NaCl x __58.448 g__ = 642.928 g of NaCl
1 mol NaCl
I would round to 642.93 g of NaCl, but round to however many significant figures asked for.
My chemistry teacher made this map (image attached) to teach us how to do conversions. Just follow the map. I think it's pretty straight forward. I hope this helps.
The total heat required to convert the ice to steam is 155,000 J.
The given parameters:
- <em>Mass of the ice, m = 50 g</em>
- <em>Initial temperature of the ice, t = -10 ⁰C</em>
- <em>Final temperature of the ice, T = 0⁰C, 100⁰C and 120⁰C</em>
- <em>Specific heat capacity of water = 4.184 J/g⁰C</em>
- <em>Heat of fusion of ice, = 333.55 J/g</em>
- <em>Heat of vaporization, = 2,230 J/g</em>
