Answer: 1.4 moles
Explanation:
I can only assume you are looking for the amount of moles in 0.4M. the capital M means Molarity.
Molarity=moles of solute/liters of solution
Since we know the molarity is 0.4, we can plug this into our equation

moles= 1.4
Non-polar because hydrophilic means something can be wetted by water
Answer : The mathematical equation used when solving calorimetry problems is:

Explanation :
Calorimetry : It is determining the changes in the energy of a system by measuring the heat transferred with surroundings.
Formula used :

where,
c = specific heat capacity of calorimeter
m = mass of a substance
q = heat required
= change in temperature of substance
It has 4 pcs of Carbon (C) and 8 pcs of Hydrogen (H) so the formula is C4H8 - calls Butene.
Hope it helps!
