James is preparing three solutions of salt water. each of the solutions has the same amount of water in the beaker and a different amounts of salt. in the first beaker, there is one scoop of salt in the beaker. the second beaker has two scoops of salt. the third beaker has three scoops of salt. which of the beakers is the most concentrated solution?

Beaker-3 with three spoon of salts is more concentrated.

Explanation:

Higher the given mass of compound in a solution, higher will be the concentration of that solution and vice versa.

Here, the beaker-1 contains one scoop of salt , beaker-2 contains two scoops of salts and beaker-3 contains three scoops of salt with equal amount of water in all the three beakers. So, the increasing order of amount of salt:

1 scoop of salt < 2 scoops of salt < 3 scoops of salt

Since, the amount of salt in in beaker-3 is highest that is with three scoops of salts. The concentration is beaker three will be higher than beaker-2 and beaker-1.

Hence, the order of increasing concentration in all beakers will be:

Beaker-1<Beaker-2<Beaker-3

third beaker

Explanation:

Binary Solution is a homogeneous mixture of two components called as solute and solvent.

Solute is the component which is present in smaller proportion and is solid for solid in liquid solution and solvent is the component which is present in larger proportion and is liquid for solid in liquid solution.

Concentrated solution is one in which there is more amount of solute.

Dilute solution is one in which there is more amount of solvent.

Thus the third beaker which has three scoops of salt has most amount of solute and is the most concentrated solution.

my dad did alot of meth and ace cheeks

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
