<u>Answer:</u> The number of atoms of bromine present in given number of mass is 
<u>Explanation:</u>
To calculate the number of moles, we use the equation:

Given mass of bromine = 1.37 g
Molar mass of bromine = 79.904 g/mol
Putting values in above equation, we get:

According to mole concept:
1 mole of an element contains
number of atoms.
So, 0.0171 moles of bromine will contain =
number of bromine atoms.
Hence, the number of atoms of bromine present in given number of mass is 
You could consider building an irrigation system.
Answer:

The answer is: mass is 40.17 kilograms.
d = 0.758 g/mL; density of fuel.
V = 14.0 gal; volume.
A gallon is a unit of volume in both the US customary and imperial systems of measurement. The US gallon is defined as 231 cubic inches (3.785 liters).
1 gal = 3785.41 mL.
V = 14 gal · 3785.41 mL:
V = 52995.74 mL.
m = 52995.74 mL · 0.758 g/mL.
m = 40170.77 g; mass of fuel.
m = 40170.77 g ÷ 1000 g/kg.
m = 40.17 kg.
