so i know that acetic acid is
the solution and i googled the molar mass for it which is 60.052,
and the mass was 59.81 so i did 59.81/60.052 which gave me the
answer 0.99597. Why is it wrong ? i dont understand, thats how you
find moles right ? mass/molar mass.

In one of the General Chemistry experiments, you used a coffee-cup calorimeter to measure the heat of neutralization of selected acid-base reactions. The calorimeter consisted of two nested Styrofoam cups with a cardboard lid. A temperature probe was lowered in the solution through a hole in the lid. Is a coffee-cup calorimeter a constant-volume or a constant-pressure device? Is a coffee-cup calorimeter adiabatic? The coffee-cup calorimeter was calibrated by using the neutralization reaction between sodium hydroxide and hydrochloric acid. The...
In a coffee-cup calorimeter, 100 mL of 1.0 M NaOH and 100.0 mL of 1.0 M HCl are mixed. Both solutions were originally at 24.6 ⁰C. After the reaction, the temperature is 31.3 ⁰C. Assuming all solutions have a density of 1.0 g/mL and a heat capacity of 4.18 J/⁰C∙g, what is the enthalpy change for the neutralization of HCl by NaOH? Assume that no heat is lost to the surroundings or the calorimeter. Enter your answer in J. I...

An aluminium block is heated to 100 °C and then placed immediately in 100 g of water which is initially at a temperature of 25.0 °C in a coffee cup calorimeter. Once the system reaches thermal equilibrium, the temperature of the water that surrounds the block is 28.0 °C. Calculate the mass of the aluminium block. The specific heat capacity of Al is 0.900 J g^–1 K^–1 and for H2O is 4.184 J g^–1 K^–1
In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. Thermometer Stirring red A student heats 68.26 grams of titanium to 99.16 °C and then drops it into a cup containing 80.78 grams of water at 23.25 °C. She measures the final temperature to be 30.68 °C. The heat capacity of the calorimeter (sometimes referred to as the...
