85.0 of is initially at room temperature (22.0). A chilled steel rod at 2.0 is placed in the water. If the final temperature of the system is 21.2, what is the mass of the steel bar? Specific heat of water = 4.18 Specific heat of steel = 0.452
My answer was 32.752. I rounded it to 32.75 and it is wrong so i rounded to 32.7, then to 32.8 all in gram and Im still wrong. Please i need help. I don't know what i am doing wrong. Thanks for your help
