An element's atomic mass does not include the mass of its <br> Electrons <br> Protons <br> Neutrons
klio [65]
  Mass  of  electrons  are not  included when  calculating  the  atomic  mass  of   element.  Atomic  mass  of  the   element  is  equal  to   proton  +  neurons.  Example  the    the  mass  number  of  Nitrogen can   be  calculated as      7 protons  +  7  neutrons  to  give 14 .  thus  nitrogen  has  a  mass  number  of  14

How many moles are there in 545g of Fe2O3 ?
Salsk061 [2.6K]
To calculate the number of moles, the equation is mass of substance divided by the molar mass of substance.

Molar mass of Fe2O3 is the relative atomic mas of all the elements from the substance added up, which makes 55.845x2 + 16.0 x3 = 159.69g mol-1

So the number of moles is
545g / 159.69gmol-1
=3.41 mol (corrected to 3 sig. fig.)

A weather balloon calibrated at 0.00 °C to
Natasha2012 [34]

Answer:

17.3 L

Explanation:

With all other variables held constant, you can find the missing volume using the Charles' Law equation:

V₁ / T₁ = V₂ / T₂

In this equation, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature. Before we can solve, we need to convert Celsius to Kelvin (because we don't want negative numbers or temp. of 0).

V₁ = 20.0 L                                            V₂ = ? L

T₁ = 0.00 °C + 273.15 = 273.15 K         T₂ = -36.2 °C + 273.15 = 236.95 K

V₁ / T₁ = V₂ / T₂                                             <----- Charles' Law equation

20.0 L / 273.15 K = V₂ / 236.95 K               <----- Insert values

0.0732 = V₂ / 236.95 K                               <----- Simplify left side

17.3 L = V₂                                                   <----- Multiply both sides by 236.95
