What is the density of a solid that has a mass of 9.2 grams and a volume of 12.3 cm3 ? Would this object float or sink in water?

cluponka [151]

Mass=9.2g
Volume=12.3

$\boxed{\sf Density=\dfrac{Mass}{Volume}}$

$\\ \sf\longmapsto Density=\dfrac{9.2}{12.3}$

$\\ \sf\longmapsto Density=0.74g/cm^3$

Density of water =1g/cm^3

It will float in water

The specific heat for liquid ethanol is 2.46 J/(g•°C). When 210 g of ethanol is cooled from

avanturin [10]

Answer:

a) heat it from 23.0 to 78.3

q = (50.0 g) (55.3 °C) (2.46 J/g·°C) =

b) boil it at 78.3

(39.3 kJ/mol) (50.0 g / 46.0684 g/mol) =

c) sum up the answers from the two calculations above. Be sure to change the J from the first calc into kJ
