Answer: A. 1.0 gallon of water
Explanation: to calculate the mass of each option, we have to note the unit conversations, and for the purposes of this question we will be using the density of the substance that is not under the condition of temperature or pressure, because we have option B which conditions of pressure and temperature are not stated.
For option A:
1gallon= 3.7854liters
Density= 1.0g/ml= 1000g/liters
mass= volume×Density
Therefore
Mass= 3.7854×1000= 3785gram
For option B:
5lb potatoes 1kg=2.2046lb
Therefore:
(5lb×1kg)/2.2046lb= 2.26798kg
Where 1kg=1000gram
(2.26798kg×1000g)/1kg= 2268grams
For option C:
1gallon=3.7854liters
Density=0.8g/ml= 800g/l
Therefore:
Mass= density×volume
Mass=800×3.7854=3028grams
For option D:
Mass= density×volume
Density= 800g/ml
Volume=3liters
Therefore mass=
800×3=2400grams
THEREFORE FROM THE OPTIONS ABOVE WE CAN SEE THAT OPTION A OF 1 GALLON OF WATER, HAS THE LARGEST MASS, WITH 3785grams

Ionization energy: the energy required to remove an electron from a neutral atom. Electron affinity: the energy change when a neutral atom attracts an electron to become a negative ion.
There are two hydrogen atoms in one molecule of water.
The answer is B) 2
Answer:
Clouds are formed when water warms up and changes into a gas called water vapor, which rises up into the air.
