How many atoms are in 3.75 moles of Fe
denis23 [38]

Answer:

2.26 × 10²⁴ atoms of Fe

Explanation:

To calculate the amount of atoms of a substance using the amount of moles, we must multiply by Avagadro's number.

(3.75mol) × (6.02 × 10²³) = 2.26 × 10²⁴ atoms of Fe

How many atoms are in 2 moles of phosphorus
Goryan [66]
Answer 2: 1 mole = 6.03 x 1023 particles. One mole of any element has a mass in grams that is equal to its atomic number, and has exactly 6.02 x 1023 atoms - however because the atoms of each element have different sizes and weights, then the volume that each one occupies is different.

A beaker contains 0.125 L of a 3.00 M solution. If the volume goes up to 0.325 L, what is the new molarity?
igor_vitrenko [27]

Answer:

1.15 M

Explanation:

Step 1: Given data

  • Initial volume (V₁): 0.125 L
  • Initial concentration (C₁): 3.00 M
  • Final volume (V₂): 0.325 L
  • Final concentration (C₂): ?

Step 2: Calculate the final concentration of the solution

We want to prepare a dilute solution from a concentrated one by adding water. We can calculate the concentration of the dilute solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁/V₂

C₂ = 3.00 M × 0.125 L/0.325 L = 1.15 M
