By using the information given below, calculate the concentration of NaOH.The volume of NaOH used in the titration = 25.00 mLVolume of 0.23 M HCl was used to neutralize the 25.0 mL NaOH = 17.7 mL. 1L = 1000 mLmolarity = moles/volume(L); moles = molarity x volume(L)NaOH + HCl –> NaCl + H2O

Solve:     5p – 2 = 23

A student measured the following data for a metallic rectangular prism.Weight = 544.341 gLength = 8.75 cmWidth = 3.22 cmHeight =1.84 cmCalculate the density of this material (1 cm3 = 1 mL) (Volume= length x width x height)

What is the volume of liquid in the graduated cylinder given below Presentation3.jpg

An unknown metal ball weighing 46.60 g was heated to 73 Celsius and placed inside a calorimeter with 60.0 g of water at 21 Celsius. After allowing the system to equilibrate, the final temperature of the water reached 31 Celsius. Calculate the specific heat of the unknown metal. Heat = mass x specific heat capacity x temperature changeSpecific heat of water = 4.184 J / (g . °C)Hint: use the following equationheat absorbs by the metal = -(heat given out by the hot water)
