1.56 moles of N2 are needed to fill a 35 L tank at standard temperature and pressure. Details about moles can be found below.
<h3>How to calculate number of moles?</h3>
The number of moles of a substance can be calculated using the following formula:
PV = nRT
Where;
- P = pressure
- V = volume
- n = number of moles
- R = gas law constant
- T = temperature
At STP;
- T = 273K
- P = 1 atm
- R = 0.0821 Latm/molK
1 × 35 = n × 0.0821 × 273
35 = 22.41n
n = 35/22.41
n = 1.56mol
Therefore, 1.56 moles of N2 are needed to fill a 35 L tank at standard temperature and pressure.

These are called ocean or underwater trenches <span />
Answer:
A
Explanation:
they move to create more energy witch keeps them moving
Answer:
They are produced from rocks (parent material) through the processes of weathering and natural erosion.
Explanation:
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
The shipping container have a density of 27.77 kg/m³.
Explanation:
The formula for density is:
density = mass / volume
volume of the container = 9 m × 4 m × 3 m
volume of the container = 108 m³
density of the container = 3000 kg / 108 m³
density of the container = 27.77 kg/m³
