A solution is prepared by dissolving 8.83 g of Na2SO4 in enough water to make 225 mL of solution. Calculate the solution molarity. 1) 0.723 M
2) 0.135 M
3) 0.276 M
4) 0.610 M

110 g of water (specific heat = 4.184 j/g c) and 100 g of a metal sample (specific heat = 0.397 j/g c) are heated from 25 degrees c to 75 degrees c. which substance required more thermal energy?
