Answer:
amount of aspirin dissolved = 0.0031 g
so we can say that this is not affect % yield as amount of aspirin lost is very less
Explanation:
given data
mass of aspirin = 1 g
volume of water = 450 mL
solubility of aspirin temperature = 10° C
volume of water added = 1.4 mL
to find out
how much amount aspirin would be lost
solution
we know the solubility of aspirin is
solubility of aspirin = 
solubility of aspirin =
solubility of aspirin = 2.2 ×
g/mL
so
we can say
amount of aspirin dissolved = solubility of aspirin × volume of water added
put here value
amount of aspirin dissolved = 2.2 ×
× 1.4
amount of aspirin dissolved = 3.1 ×
g
amount of aspirin dissolved = 0.0031 g
so we can say that this is not affect % yield as amount of aspirin lost is very less
Seriously? It’s that hard to use a calculator??
Answer:
<h3>The answer is 4 N</h3>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 2 × 2
We have the final answer as
<h3>4 N</h3>
Hope this helps you
Answer:
The variation in apparent gravitational acceleration (g) at different locations on Earth is caused by two things (as you implied). ... The distance between the centers of mass of two objects affects the gravitational force between them, so the force of gravity on an object is smaller at the equator compared to the poles.
