An atom of gold has a mass of 3.271 x 10-22g. How many atoms of gold are in 5.00g of gold?
rosijanka [135]
To get the number of gold atoms, you have to divide the mass of the gold by the mass of the gold atom. It follows this simple equation  \frac{mass of gold}{mass of gold atom}. 

Let x be the number of gold atoms. Plug in the values to a calculator.

x = \frac{5.00g}{3.271 x 10-22g}
Both have the same units so the unit gram(g) can be cancelled. 
x then would be equal to 1.53x10^22. So there are 1.53x10^22 atoms of gold in 5 g of gold

What mass of cucl2 is contained in 75.85 g of a 22.4% by mass solution of cucl2 in water?
Sindrei [870]
First  step: convert   22.4%  into   fraction
 that  is  22.4/100  which  is equivalent  to 0.224
  The  mass  of Cucl2  contained  in  75.85  of  22.4%  by  mass  of   solution  of  CUcl2 in  water is   therefore,
0.224 x75.85=16.99g
alternatively
75.85 --->100%
      ?        22.4%
by cross  multiplication =(22.4 x 75.85)/100 =16.99g
