Calcium chloride has a heat of solution listed as -81.3 kJ/mol when dissolved in water. Using this, suppose we dissolve 10.0 g of calcium chloride in 50.0 mL of water at 25 degrees Celsius. What will be the new temperature of the water? (assume that Csolution = 4.18 J/g degrees Celsius)

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
