The density of air surrounding the balloon may be calculated by assuming that air is an ideal gas and using the equation,
PV = nRT
In terms of density,
density = PM/RT
Using the given data,
density = (1 atm)(28.84 g/mol)/(0.0821 L.atm/molK)(20+273K) = 1.20 g/L
Using ratio and proportion,
density of balloon = 0.577 g/ V = 1.20 g/L
The volume is equal to 0.48 L.
80 minutes because:
1600 -> 20mins -> 800
800 -> 20 mins -> 400
400 -> 20 mins -> 200
200 -> 20 mins -> 100
4*20 mins = 80 minutes
Answer:
There are 0.1 moles of solute in 250 mL of 0.4 M solution
Explanation:
because it is
Answer: A
The protons in the nucleus repel each other
Explanation:
the number of protons inside a nucleus increases the electrostatic repulsion between protons increase reducing the binding energy. Thus the electrostatic force determines the stability of a nuclear configuration
