Calculating Needed Volume of 15 g/L Salt Solution for 12 g/L Solution

AI Thread Summary
To create a 50 ml solution with a concentration of 12 g/L from a 15 g/L salt solution, the calculation involves using the formula C1 * V1 = C2 * V2. The correct volume needed from the 15 g/L solution is 0.04 L, or 40 ml. Initially, there was confusion regarding the calculation, but it was clarified that the mistake was a simple error on paper. The discussion highlights the importance of double-checking calculations in solution preparation. Accurate volume measurements are crucial for achieving the desired concentration in solution chemistry.

A salt solution has a concentration of 15 g/L. How much of this solution is needed to make 50 ml of a solution which has a concentration of 12 g/L.

Using C_1 * V_1= C_2* V_2(concentration and volume) I got .4 L of this solution must be added.
I didn't really know how to tackle this one so maybe (if I'm wrong, which I probably am) could someone help me out?

NO,the answer should be 0.04L=40mL.Maybe that's what u've gotten and what u've written is just a typo...

Ya, it wasn't a typo in my post, it was just a silly mistake on paper, but I found it. Thanks dexter.
 

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...

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}...
