Answer:

9.4 liter

Explanation:

V₁ = 10.0 L

T₁ = 25°C = 25 + 273.15 K = 298.15 K

P₁ = 98.7 Kpa

T₂ = 20°C = 20 + 273.15 K = 293.15 K

P₂ = 102.7 KPa

V₂ = ?

<u>2) Formula:</u>

Used combined law of gases:

PV / T = constant

P₁V₁ / T₁ = P₂V₂ / T₂

<u>3) Solution</u>:

Solve the equation for V₂:

V₂ = P₁V₁ T₂ / (P₂ T₁)

Substitute and compuite:

V₂ = P₁V₁ T₂ / (P₂ T₁)

V₂ = 98.7 KPa × 10.0 L × 293.15 K / (102.7 KPa × 298.15 K)

V₂ = 9.4 liter ← answer

1) How many moles are in 4.0x10^24 atoms?

-Dominant- [34]

Answer:

<h2>6.64 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

$n = \frac{4 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 6.644518...$

We have the final answer as

<h3>6.64 moles</h3>
