You just have to find a conversion from amu to grams. For every 1 amu, there is 1.66×10⁻²⁴ grams. Thus,
Mass of proton = 1.0073 amu * 1.66×10⁻²⁴ grams/amu = 1.672×10⁻²⁴ grams
Since a proton is spherical in shape, the volume would be:
Volume = 1/6*πd³ = 1/6*π(1.0×10⁻¹⁵ cm)³ = 5.236×10⁻⁴⁶ cm³
Therefore, the density is equal to
Density = Mass/Volume = 1.672×10⁻²⁴ grams/5.236×10⁻⁴⁶ cm³
Density = 3.2×10²¹ g/cm³

Answer: Option 1, 4 and 5 describe acids accurately.
Explanation:
Option 1: Acids have a sour taste because of the concentration of 
ion.
Option 2: They are corrosive in nature, that is they are not at all gentle with the skin and fabric as some acids intend to burn skin such as 
is a strong acid which can burn skin as well as fabric.
Option 3: Acids need electrons to release ions and non-metals do not donate electrons hence, there is no reaction between a non-metal and an acid.
Option 4: All acids do contain hydrogen. They dissociate in the presence of water to produce ions.
Option 5: Acids do conduct electricity that is they carry electrical charges. This was explained by Arrhenius. He said that the acids dissociate into ions, when it is dissolved in water. These ions hence acts as charge carriers in water.
Answer:
%age Yield = 20.12 %
Solution:
The Balance Chemical Reaction is as follow,
Cl₂ + 3 F₂ → 2 ClF₃
According to Equation ,
114 g (3 mole) F₂ produces = 184.88 g (2 moles) of ClF₃
So,
19.2 g of F₂ will produce = X g of ClF₃
Solving for X,
X = (19.2 g × 184.88 g) ÷ 114 g
X = 31.13 g of ClF₃ (Theoretical Yield)
As we know,
%age Yield = (Actual Yield ÷ Theoretical Yield) × 100
%age Yield = (6.3 g ÷ 31.3 g) × 100
%age Yield = 20.12 %
