Answer:
The mass left after 24.6 years is 25.0563 grams
Explanation:
The given parameters are;
The mass of the hydrogen-3 = 100 grams
The half life of hydrogen-3 which is also known as = 12.32 years
The formula for calculating half-life is given as follows;
Where;
N(t) = The mass left after t years
N₀ = The initial mass of the hydrogen-3 = 100 g
t = Time duration of the decay = 24.6 years
= Half-life = 12.32 years
The mass left after 24.6 years = 25.0563 grams.
C) 22 because the mass of a neutron is 1 amu and a proton is also 1 amu, so 40-18=22
I think the correct answer would be Kabuki. It is a Japanese traditional form of theater that is characterized by the heavy make-up worn by the performers. It started during the Edo Period. It is one of the major classical theater in Japan.
Answer:
Molecular formula = H₂S₂O₈
Explanation:
Given data:
Empirical formula = HSO₄
Formula mass = 194.13 amu
Molecular mass = ?
Solution:
Molecular formula = n × empirical formula
n = molar mass of the compound / empirical formula mass
Empirical formula mass = 1.008 + 32.065 + 16× 4
Empirical formula mass = 97.073
n = 194.13 / 97.073
n= 2
Molecular formula = n × empirical formula
Molecular formula = 2 (HSO₄)
Molecular formula = H₂S₂O₈
The answer to your equation is C. Hope this Helps!
