Answer:
The answer to your question is Molarity = 0.41
Explanation:
Data
mass of KNO₃ = 76.6 g
volume = 1.84 l
density = 1.05 g/ml
Process
1.- Calculate the molecular mass of KNO₃
molecular mass = 39 + 14 + (16 x 3) = 101 g
2.- Calculate the number of moles
101 g of KNO₃ --------------- 1 mol
76.6 g of KNO₃ ------------ x
x = (76.6 x 1) / 101
x = 0.76 moles
3.- Calculate molarity
Molarity = 
Substitution
Molarity = 
Result
Molarity = 0.41
Answer:
1. Two people stand on the same side of a large tire. Both people pull the tire with equal force.
2. an object’s ability to not change its motion
3. The car moves forward, while inertia keeps the balloon in place.
4. The unbalanced forces of air resistance and gravity slow the airplane and pull it down.
5. The force acting on the object must be unbalanced.
<u>We are given:</u>
The force applied on the poor hamster (F) = 12 N
Acceleration of the poor Hamster (a) = 8 m/s²
<u>Solving for the mass of the Poor Hamster:</u>
From newton's second equation of motion, we know that:
F = ma
<em>replacing the given values</em>
12 = 8 * m
m = 12/8 kg
m = 3/2 kg
The poor Hamster weighs 3/2 kg
Answer:
It depends what other values you have. Can you give more info? If they give density then you can solve for m.
it would be 26 because once you divide 160g by 5.0g and add 12.5 you would get 26
hope this helps
