If you dissolve 50.0 grams of potassium bromide in 100.0g of water what is the mass percent of the resultant solution?

Mass percent= grams solute/ grams of solution x 100

Mass Percent= (50/ 150)x100= 33.3%

12 is probably the typical age for a first kiss but i think its to young.

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
