Speed of the car = 
Given time = 37.0 s
Converting time from seconds to hours:
1 hr= 60 min; 1 min = 60 s

Calculating distance from speed and time:

Converting distance from km to m:

So the distance traveled by the car in 37.0 s is 894 m.
Answer:
1.01 atm
Step-by-step explanation:
To solve this problem, we can use the <em>Combined Gas Laws</em>:
p₁V₁/T₁ = p₂V₂/T₂ Multiply each side by T₂
p₁V₁T₂ = p₂V₂ Divide each side by V₂
p₂ = p₁ × V₁/V₂ × T₂/T₁
Data:
p₁ = 1.05 atm; V₁ = 285 mL; T₁ = 15.8 °C
p₂ = ?; V₂ = 292 mL; T₂ = 11.2 °C
Calculations:
(a) Convert <em>temperatures to kelvins
</em>
T₁ = (15.8+273.15) K = 288.95 K
T₂ = (11.2+273.15) K = 284.35 K
(b) Calculate the <em>pressure
</em>
p₂ = 1.05 atm× (285/292) × (284.35/288.95)
= 1.05 atm × 0.9760 × 0.9840
= 1.01 atm
Answer: -
The concentration is 0.91 mol/ L
Explanation: -
The osmotic pressure = 23 atm
Absolute temperature = 309 K
Universal gas constant = 0.08206 L atm mol⁻¹ K⁻¹
We know the formula
Osmotic pressure = molar concentration x universal gas constant x absolute temperature
Plugging in the values
23 atm = molar concentration x 0.08206 L atm mol⁻¹ K⁻¹ x 309 K
Molar concentration =
mol/ L
= 0.91 mol / L
