The calculations outline in the procedure do not account for the warming of the melted ice to the final temperature. How much energy in joules is required to warm 25.0 grams of water from 0.0°C to 6.2 C? By comparison, melting 25.0 g of ice requires 8340 J of heat. Your Answer:

Е. NaCN Br Acetone

1a. Determine the volume of 1.000 g of water (Densitywater = 0.9999 g/mL). 1b. Determine the volume of 1.000 g of ice (Density ce = 0.9168 g/cm³). (1 mL = 1 cm³) %3D %3D 1c. From the volumes above, what can we conclude about 1.000 g of water when it freezes?

Newly produced beer must be checked to see if it meets predetermined standards. The percentage of alcohol is determined by distillation. A set of measurements is listed forone batch.Sample Volume of beer (L) Ethanol distilled (mL)1               8.00                         3922              10.00                          5003              9.00                            4594             9.00                           444 What is the average percentage by volume of ethanol for this batch?
