Explanation:
The scenario that contains an exact number is 'A) You count 10 people in a room' (Option A).
<h3>What is the exact number?</h3>
An exact number can be considered a discrete variable because it does not involve a continuous range of values in a given measurement.

Answer:
5.8 L
Step-by-step explanation:
This looks like a case where we can use the <em>Combined Gas Law</em> to calculate the temperature.
p₁V₁/T₁ = p₂V₂/T₂ Multiply both sides by T₂
p₁V₁T₂/T₁ = p₂V₂ Divide each side by V₂
V₂ = V₁ × p₁/p₂ × T₂/T₁
=====
<em>Data</em>:
p₁ = 5.6 atm
V₁ = 20 L
T₁ = 35 °C = 308.15 K
p₂ = 23 atm
V₂ = ?
T₂ = 95 °C = 368.15 K
=====
<em>Calculation:
</em>
V₂ = 20 × 5.6/23 × 368.15/308.15
V₂ = 20 × 0.243 × 1.19
V₂ = 5.8 L

Explanation:
Hello!
In this case, considering the Avogadro's number, which relates the number of particles and one mole, we can infer that 1 mole of any element contains 6.022x10²³ atoms as shown below:
Thus, we compute the number of atoms in 0.035 moles as shown below:
