what is the volume of a solution that has a density of
1.20 g/mL and a mass of 153 g?
what is a density of a liquid that has a mass of 2.638 g and a volume of 3.945 mL?
how many calories of heat are required to raise the temperature of 193 g of water from 25.0 C to 73.4 C? specific heat of water is 1.00 cal/g C
density = 1.20g/ml
mass = 153 grams
we know density = mass / volume
then volume of the solution = mass / density = 153 g / 1.20g/ml = 127.5ml
mass = 2.638g
volume = 3.945ml
we know density = mass / volume = 2.638g / 3.945 ml = 0.668g/ml
mass = 193g
specific heat = 1 cal/g.0c
T1 = 250c & T2 = 73.40c
heat = mass * specific heat * change in temperature
q = m * s * (T2 - T1)
q = 193 g * 1.00 cal/g 0c * (73.4 - 25) = 9341.2 cal
