Answer:
Explanation:
a )
m = m₀
m is mass after time t . original mass is m₀ , λ is disintegration constant
λ = .693 / half life
= .693 / 1590
= .0004358
m = m₀
b )
m = 50 x
= 40.21 mg .
c )
40 = 50
.8 =
= 1.25
.0004358 t = .22314
t = 512 years .
Answer:
The value is
Explanation:
From the question we are told that
The mass of saxitoxin is
The volume of water is
The osmotic pressure is
The temperature is
Generally the osmotic pressure is mathematically represented as
Here R is the gas constant with value
and C is the concentration of saxitoxin
So
Generally the number of moles of saxitoxin is mathematically represented as
=>
=>
Generally the molar mass of saxitoxin is mathematically represented as
=>
=>
