A rock has the density of 8g/ml. If the rocks mass is 2g what is the rocks volume ?

1/4 ml

Explanation:

Density=8g/ml

Mass=2g

Volume=mass/density

Volume=2/8

Volume=1/4 ml

Volume = 0.25 mL

Explanation: Density is expressed as mass of the object per unit volume. So derive for volume,

d = m/ V

Volume is expressed as mass divided by density or V = m /d

V = 2 g / 8 g /mL

= 0.25 mL

Cancel out the unit in grams and the remaining unit is in mL.

passed in september 1935, these laws are known as nuremberg laws.   they forbid jews from marrying but not directly forced them to divorce aryans. what is most noticeable is the fact that the jews were defranchised, meaning by this that they were not expected to have any civil rights, including the right to vote. the right answer is deprived of the right to vote.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
