Electromagnets are devices that create a magnetic field through the application of electricity. Strong electromagnets are used to lift, move and drop heavy objects, such as vehicles. Electromagnets have advantages over permanent magnets. When the current is switched off, the electromagnet will lose its magnetism. The car will fall back to earth and we need that when we move cars in a junkyard. With a regular ( permanent ) magnet it would be much harder to do.

What quantity of a 65% acid solution must be mixed with a 25% solution to produce 600 mL of a 45% solution?

soldier1979 [14.2K]

Lets say x is quantity
65%x+25%(600-x)=45%of 600
.65x+.25(600-x)=.45*600
.65x+150-0.25x=270

x<16/3

x<5
