4 Fe + 3 O2 → 2 Fe2O3 How many moles of Fe are needed to react with 1.00 moles of O2?
Group of answer choices

1.0 mol

3.0 mol

1.3 mol

4.0 mol

c. 75.7

i think that is the right

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i  

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
