A chemist has 3.55x1022 molecules of nitrogen monoxide. How
Alina [70]

Answer:

<h2>0.059 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{3.55 \times  {10}^{22} }{6.02 \times  {10}^{23} }  \\  = 0.05897...

We have the final answer as

<h3>0.059 moles</h3>

Hope this helps you

117 mL of 0.210 M K₂S solution

Explanation:

The question asks about the volume of 0.210 M K₂S (potassium sulfide) solution required to completely react with 175 mL of 0.140 M Co(NO₃)₂ (cobalt(II) nitrate).

We have the chemical reaction:

K₂S + Co(NO₃)₂ → CoS + 2 KNO₃

molar concentration = number of moles / volume (L)

number of moles = molar concentration × volume

number of moles of Co(NO₃)₂ = 0.140 × 175 = 24.5 mmoles

We see from the chemical reaction that 1 mmole of Co(NO₃)₂ is reacting with 1 mmole of K₂S, so 24.5 mmoles of Co(NO₃)₂ are reacting with 24.5 mmoles of K₂S.

volume = number of moles / molar concentration

volume of K₂S solution = 24.5 / 0.210 = 117 mL
