In determining safe speed of a vessel we must consider visibility, traffic density etc.
<h3>What is safe speed?</h3>
The safe speed of a vessel is the maximum speed the vessel can be operated to avoid hazards such as collision, damage of vessel, etc.
<h3>Factors considered when determining safe speed of vessels</h3>
In determining safe speed of a vessel we must consider the following factors such as;
- Weather condition, eg visibility
- Traffic density,
- Background light at night, etc
Thus, in determining safe speed of a vessel we must consider visibility, traffic density etc.

The following are true of mole ratio
- They are expressed as ratio of mass to molar mass
- It is measured in moles
<h3>How to calculate the mole ratio</h3>
The formula for calculating the mole ratio is expressed according to the formula shown:
Mole ratio is the ratio of the mass of a substance to the molar mass of the same substance.
To calculate the mole ratio
Mole = Mass(g)/molar mass(g/mol)
Hence the following are true of mole ratio
- They are expressed as ratio of mass to molar mass
- It is measured in moles
