How many grams of Carbon dioxide (CO2) are needed to create a 40M
solution in 150ml of solution?

a) 264
b) 0.14
c) 26.4
d) 0.27

264 grams of Carbon dioxide (CO2) are needed to create a 40M  solution in 150ml of solution.

Explanation:

Given :

molarity of the solution = 40M

Volume of the solution = 150ml or 0.15 litres after dividing it by 1000

compound is carbon dioxide

atomic mass of CO2 = 44.01 gram/mole

mass of CO2 = ?

moles of Co2 =?

the relation between grams and molarity is given by:

number of moles =  equation 1

molarity is given by :

Molarity =  equation 2

 Putting the value of number of moles in equation 2

molarity =

mass = molarity x atomic mass x volume

mass = 40 x 0.15 x 44.01

         = 264 grams

264 grams is the mass of carbon dioxide required to make a solution of 40 M in 150 ml of solution.

answer: i dont know the answer but this might

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
