A9.35g sample of a solid was placed in a 15.00ml flask. the remaining volume was filled with benzene in which the solid is insoluble. the solid and benzene together weigh 17.33 g. the density of benzene is 0.876 g/ml. what is the density of the solid?

 1.58 g/ml

Explanation:

Given :Total mass= 17.33 g

Mas of solid = 9.35 g

Thus Mass of benzene = Total mass - Mass of solid= (17.33-9.35)g= 7.98 g  

Density of benzene = 0.876 g/ml

Therefore  Volume of benzene =

Total volume = 15 ml

Volume of solid = Total volume - Volume of benzene= (15-9.1)=5.9ml

Thus Density of solid=

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

yes it is balanced
