AI Thread Summary
To convert the mass of Cobalt-60 from micrograms to moles, the atomic mass of Cobalt-60 (59.933817059 u) is used to determine the molar mass in grams per mole, which is approximately 59.934 g/mol. Given a mass of 1 microgram (1μg), the formula n = m/M can be applied, where n is the number of moles, m is the mass in grams, and M is the molar mass. Converting 1μg to grams gives 1 x 10^-6 g, and dividing this by the molar mass results in approximately 1.668507 x 10^-8 moles of Cobalt-60. This calculation confirms the correct application of the formula for converting mass to moles.

This is not a question from a book.

I know that Cobalt-60 has the atomic mass of 59.933817059u. How can I get the amount of moles in 1μ Cobalt-60?

I know that ##n=\frac{m}{M}## but I can't really ply it here it seems.
Can anyone help me please?

I don't see why it can't be applied here.

Alright so I have the mass which is 1μg. But how can I turn that u thingy into M?
 
Doesn't M=59.934 g/mol ?

Then there is 1.668507... × 10^-8mols in 1 microgram Co-60. Thank you.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
