Answer: I'm thinking it should be either stay the same or decrease
Explanation: If the size is increasing then the sample should not increase but decrease or stay the same. Mainly the sample would do the opposite of what the size is doing
Answer: The molality of solution is 17.6 mole/kg
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.
where,
n = moles of solute
= weight of solvent in kg
moles of acetone (solute) = 0.241
moles of water (solvent )= (1-0.241) = 0.759
mass of water (solvent )= 
Now put all the given values in the formula of molality, we get
Therefore, the molality of solution is 17.6 mole/kg
1.21:1 = 22.4 : x where x is the amount of fluorine produced.
So answer is 22.4 / 1.21 = 18.51
Answer:
E = 8.84×10⁻¹⁷ J
Explanation:
Given data:
Wavelength of wave = 2.25 nm (2.25×10⁻⁹ m)
Energy of wave = ?
Solution:
Formula:
E = hc/λ
c = 3×10⁸m/s
h =6.63 ×10⁻³⁴ Js
now we will put the values,
E = 6.63 ×10⁻³⁴ Js × 3×10⁸m/s / 2.25×10⁻⁹ m
E = 19.89×10⁻²⁶ Jm / 2.25×10⁻⁹ m
E = 8.84×10⁻¹⁷ J
