         step  one;  calculate  mass
Mass=density   x volume
    1ml=1cm^3
   13.69g/cm^3  x  17  cm^3=232.73g

  step  2;  calculate  the   number of  moles  of   mercury
(232.73g/200.59g/mol)(molar  mass  of mercury=  1.1602moles
  
by  use   of  avogdros  law
1moles =6.023E23  atoms
what about  1.1602moles
=1.1602 x 6.023E23=  6.988E23atoms

horrorfan [7]

the metric system is that volume is derived from the basic length measurement

mL and cm^3

What is metric system?

A system of measurements is called the metric system. It is employed in calculations and research across the globe. Here are some instances of measurements made with the metric system:

  • The unit used to measure lengths and distances is the meter. In daily life, we use this unit to measure things like the length of a piece of clothing, the distance from school to home, etc.
  • You may have noticed that the bag of your favorite food has a weight listed on it. 250 grams of potato chips, as an illustration. The unit of weight used here is the gram.
  • Similar to this, the bottle of your preferred beverage has a volume indication (for example, 250 milliliters of cola). The unit of volume used here is the milliliter.

What volume would be occupied by 8.1 g of a substance with a density of 1.65041 g/cm3 ? answer in units of cm3 ?
ladessa [460]
Hey there!

Mass = 8.1 g

density = 1.65041 g/cm³

Volume = ?

Therefore:

D = m / V

<span>1.65041  = 8.1 / V

V = 8.1 / </span><span>1.65041 g

V = 4.907 cm</span>³
