a) Mass of gasiline = 18.9 kg; b) distance travelled = 204 mi
a) <em>Mass of gasoline
</em>
<em>Step 1</em>. Convert <em>$CDN to $US</em>
$US = $30.00 CDN × (0.942$US/$1 CDN) = $28.26 US
<em>Step 2</em>. Calculate the <em>volume of gasoline
</em>
V = $28.26 US × (1 gal gasoline/$3.82 US) = 7.399 gal
<em>Step 3</em>. Convert <em>gallons to litres
</em>
V =7.399 gal × (3.785 L/1 gal) = 28.00 L
<em>Step 4</em>. Calculate the <em>mass of the gasoline
</em>
Mass = 28 000 mL × (0.674 g/1 mL) = 18 900 g = 18.9 kg
<em>
b) Distance travelled
</em>
<em>Step 1</em>. Calculate the <em>kilometres</em>
Kilometres = 28.00 L × (100 km/8.53 L) = 328.3 km
<em>Step 2</em>. Convert <em>kilometres to miles</em>
Miles = 328.3 km × (1 mi/1.609 km) = <em>204 mi</em>
Hope this help you!!! :))
Answer:
32.25 J
Explanation:
Heat, H = ?
Mass, m = 5g = 5 / 1000 = 0.005 Kg
Initial Temperature = 75.0° C
Final Temperature = 25.0° C
Temperature change, ΔT = Final - Initial = 50° C
Specific heat capacity of lead, C = 129 (J/kg°C)
The relationship between these quantities is given by the equation
H = mCΔT
H = 0.005 * 129 * 50
H = 32.25 J
Answer:
Fundamentally, chemistry is the study of matter and change. The way that chemists study matter and change and the types of systems that are studied varies dramatically. Traditionally, chemistry has been broken into five main subdisciplines: Organic, Analytical, Physical, Inorganic and Biochemistry.
