Answer: 3378.4mL
Explanation:
density of Gasoline = 0.74g/mL.
Volume of gasoline in milliliter = ?
mass of gasoline = 2.5kg
(Since density is in grams per millilitre, convert mass in kilograms to grams)
If 1kg = 1000grams
2.5kg = 2.5 x 1000 = 2500grams
Recall that density is obtained by dividing the mass of a substance by its volume
i.e Density = Mass / Volume
0.74g/mL = 2500grams/Volume
Volume = (2500 grams / 0.74g/mL)
Volume = 3378.4mL
Thus, the volume of gasoline is 3378.4mL
Answer:
42 m/s
Explanation:
To we convert units for speed we can use dimensional analysis. First thing we do is seperate the measurement into a fraction. After this we can multiply by 1km over 0.62137 miles. We do this so that the miles cancel out.
×
= 
After this we can use a conversion factor and divide by 3.6.
÷ 3.6 = 42 m/s
0.7 my teacher just gave me the answer i got too lazy to explain why
Answer:
The volume is 50, 74 liters
Explanation:
We use the formula PV = nRT. The temperature in Kelvin is = 273+ 20 =293K
PV=nRT ---> V = (nRT) / P
V= (2.0 mol x 0,082 l atm /K mol x 293 K) / 0,947 atm
V=50,74128828 l
