Question
A sample of sand initially at 22.3°C absorbs 1.34 x 10^3 J of heat. The final temperature of sand is 67.8 °C. What is the (in g) of sand in the sample? Round to the nearest whole number.

q = mcdT
1.4E3J = mass sand*specific heat sand*(Tfinal-Tinitial). You need to know the specific heat of the sand. Then plug in the numbers and solve for mass sand.
