Plug in what you know
-Heat (q) is 2520
-Delta T (change in temperature) is 70-10 which is 60
-Mass (M) is 10kg
-specific heat (c) is unknown.
2520 = (10)C(60)
Use algebra to solve for C.
Multiply C by 60 and 10.
2520 = 600C
Divide both sides by 600 to get C by itself.
C = 4.2 J/g
The percent given is in terms of volume so the solution contains 40 mL of alcohol per 100 mL of the solution. Multiplying the given amount of solution to the percentage, we will obtain the amount of alcohol.
620 mL solution ( 40 mL alcohol / 100 mL solution ) = 248 mL alcohol
