The amount (in pounds) the gasoline tank will hold when full is 153.76 lb
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
<h3>How to convert gallon to milliliters </h3>
1 gallon = 3785.412 mL
Therefore,
25 gallon = 25 × 3785.412
25 gallon = 94635.3 mL
<h3>How to determine the mass </h3>
- Density = 0.737 g/mL
- Volume = 94635.3 mL
- Mass =?
Mass = Density × Volume
Mass = 0.737 × 94635.3
Mass = 69746.2161 g
<h3>How to convert grams to pounds </h3>
453.592 g = 1 lb
Therefore,
69746.2161 g = 69746.2161 / 453.592
69746.2161 g = 153.76 lb

Answer:
1) Condensation.
2) See below.
Explanation:
1) The warmer water vapour from the surroundings came into contact with the cooler inner surface of the glass jar and condensed, forming the water droplets (water vapour) on the inside of the glass jar.
2) As condensation occurs, condensed water vapour will drip into the water solution in the glass jar, causing the water to rise in the glass jar.
Answer:
Explanation:
Given data:
Mass of N₂ = 48.7 g
Moles of N₂ = ?
Molecules of N₂ = ?
Mass of N₂O = ?
Moles of N₂O = ?
Atoms of N₂O = ?
Solution:
Chemical equation:
2N₂ + O₂ → 2N₂O
Number of moles of N₂:
Number of moles = mass/ molar mass
Number of moles = 48.7 g / 28 g/mol
Number of moles = 1.74 mol
Number of molecules of N₂:
1 mole = 6.022 × 10²³ molecules
1.74 mol× 6.022 × 10²³ molecules/1 mol
10.5 × 10²³ molecules
Now we will compare the moles of N₂ with N₂O from balance chemical equation:
N₂ : N₂O
2 : 2
1.74 : 1.74
Moles of N₂O:
1.74 mol
Mass of N₂O:
Mass = number of moles × molar mass
Mass = 1.74 mol × 44 g/mol
Mass = 76.56 g
