AI Thread Summary

To calculate the amount of NaCl in a 500ml saline solution, the density of the solution must be known, as the relationship between volume (ml) and mass (grams) requires this information. Given the ratio of 10 grams of NaCl to 100 grams of water, the total mass of the solution can be determined if the density is provided. Once the total mass is known, the mass of NaCl can be calculated using the defined ratio. Without the density, the calculation cannot be accurately completed. Understanding the relationship between volume, mass, and concentration is crucial for such calculations.

Say for example you have take a sample of 500ml from a bulk saline solution (NaCl and H20). If you know that for every 100 grams of water there is 10 grams of NaCl, can you calculate the amount of NaCl in 500ml of the final mixture?

I think you'd need to know the densities since ml is volume and grams is mass

Thread 'Is space stretching or is new space being created?'

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
