Answer:
4.76×10¯⁵ cm
Explanation:
We'll begin by converting 476 nm to m. This can be obtained as follow:
1 nm = 1×10¯⁹ m
Therefore,
476 nm = 476 nm × 1×10¯⁹ m / 1 nm
476 nm = 4.76×10¯⁷ m
Finally, we shall convert 4.76×10¯⁷ m to cm. This can be obtained as follow:
1 m = 100 cm
Therefore,
4.76×10¯⁷ m = 4.76×10¯⁷ m × 100 cm / 1 m
4.76×10¯⁷ m = 4.76×10¯⁵ cm
Thus,
476 nm = 4.76×10¯⁵ cm
C a solution because salt is a solute
<span>Out of the options here, the most suitable units that could be used for representing density would be option c) g/cm. Density is a value for mass (in this case g) divided by a value for volume (in this case cm). Option E, kg/L, would also work.</span>
When two aqueous solutions are mixed together and the temperature of the solution decreases, the reaction is called an endothermic reaction with a positive enthalpy change. Endothermic reaction is when heat is absorbed by the reaction taking place. All endothermic reaction always have a positive enthalpy change.
