The volume at STP : 9.856 L
<h3>Further explanation</h3>
Given
Mass of ethane : 13.21 g
Required
The volume at STP
Solution
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
mol ethane(C2H6) :
= mass : molar mass
= 13.21 g : 30 g/mol
= 0.44
Volume at STP :
= 0.44 x 22.4 L
= 9.856 L
Answer:
The primary type of energy change which occurs by turning on the phone will be the conversion of the stored chemical energy of the battery into electrical energy. The chemical energy is also converted into light energy, sound energy and heat energy. With the passage of time, the energy will be changed back into the chemical energy when we will charge the phone again.
