I think air but if wrong sorry
<span>1 fm = 1.0 × 10-15 meters
</span>so
0.610<span> fm x (1.0x10^-15 m / 1 fm)
= 6.1x10^-16 m</span>
so the formula is
λ = h / mu
so,
as we know mass value so by putting
<span>m = (6.626*10^-34)/(6.1*10^-16*199)
=</span>(6.626*10^-34)/(1213.96*<span>10^-16)
</span><span> = 5.45 x 10^ -21
hope thats an answer for you</span>

Answer:
The solid crystals disappeared
Explanation:
When a soluble solid solute is added to water, the solid solute disappears after a little while. The disappearance of this solute indicates that the solute has been dissolved in water.
In this case, blue copper sulphate crystals are added to water, the blue crystals disappear leaving only a blue solution. The disappearance of these blue copper sulphate crystals indicates that the substance has dissolved in water.
