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

=> 
=> 
The density of gasoline is 0.7 g/cm3, and the density of water is 1 g/cm3. Thus the mass of the gasoline is 55*0.7 = 38.5g and the mass of the water is 60g.
Combining the 55 cm3 and 60 cm3 of substances with the aforementioned masses yields a volume of 55+60 = 115cm3 and a mass of 38.5+60 = 98.5g. The density is therefore 98.5/115 = 0.86 g/m3.
Answer:
n order to find the velocity of the moving object, you will need to divide the change in position by the change in time. Specify the direction moved, and you have the average velocity
Mass witch would be c i covered this in class
Answer:
Hopefully its true, its seem like true. I think its true. Sorry if i'm wrong
