Calculate the density in g/ml of 2.0 L of gasoline that weighs 1.32 kg
sveta [45]

Answer: 0.66 g/mL

Explanation: The formula for density is d= m/v where m=mass and v=volume.

The mass was given in the problem, m= 1.32kg

The volume was also given in the problem, v= 2.0L

d= m/v ---> d= 1.32kg/2.0L ---> d=0.66kg/L

The problem calls for the answer to be written in g/mL, so we must convert the units. 1 kg contains 1000g and 1 L contains 1000 mL.

1000g/1000mL = 1 so the units change but the 0.66 does not. Therefore, your answer is 0.66g/mL (Two significant figures because 2.0 only has 2 significant figures).

Water vapor is condensed steam. <br><br> True <br> False
adelina 88 [10]

False, because water vapor, water vapour or aqueous vapor, is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Unlike other forms of water, water vapor is invisible.

Polar bonds
nika2105 [10]

Answer: a. Have an overall neutral charge

b. Have electrons that are not equally shared

d. Have slight positive and negative ends

Explanation:

Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. Example: HCl

The more electronegative element i.e. chlorine acquires a partial negative charge as it withdraws the electron density towards itself. Thus hydrogen acquires a partial positive charge. The opposite charges cancel each other and thus overall it is electrically neutral.
