Start with the initial solution here.
00:02
We use the formula q is equal to mc delta t.
00:06
We're going to solve for q here.
00:08
So initially we have 10 grams of the ionic salt.
00:14
No, 100 milliliters of water.
00:22
So 100 milliliters of water is equal to 100 grams of water.
00:29
It has a density of h2o.
00:31
We know is 1 gram per milly.
00:34
So this is 100 grams of water, heat capacity of water.
00:40
We can look up is 4 .184 joules per gram degrees celsius.
00:48
Change in temperature there is 24 degrees celsius.
00:52
This gives me 10 ,004 .1 .6 joules.
01:03
And then the salt here, delta h is equal to q over the mass of the salt, 10 .4 .1 .6 joules over 10 .0 grams gives me 1 ,0 .16 joules per gram...
