How many moles of iron are in 4.8 x 10^24 atoms of iron

7.97 moles

Explanation:

The number of moles (n) of iron (Fe) in this question can be calculated by dividing its number of atoms by Avogadro's number (6.02 × 10²³ atoms).

That is;

n = number of molecule ÷ Avogadro's number

According to this question, the number of atoms of Fe is given as 4.8 x 10²⁴ atoms.

Hence,

n = 4.8 x 10²⁴ ÷ 6.02 × 10²³

n = 4.8/6.02 × 10^(24-23)

n = 0.797 × 10¹

n = 7.97 moles

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.  

explanation:

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
