The answer is mean,mode and median
Answer: There are 
formula units
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
1 mole of 
contains = formula units
Thus 0.38 moles of contains = 
formula units
Thus there are formula units
Answer:
2J/g°C
Explanation:
Q = 5000J
Initial temperature (T1) = 20°C
Final temperature (T2) = 70°C
Specific heat capacity (c) = ?
Heat energy (Q) = mc∇T
Q = mc∇T
Q = mc(T2 - T1)
5000 = 50 × c × (70 - 20)
5000 = 50c × 50
5000 = 2500c
c = 5000 / 2500
c = 2J/g°C
The specific heat capacity of the substance is 2J/g°C
