The "sea of instability" refers to a region of elements on the periodic table that are highly unstable. These elements have extremely short half-lives that may be measured in micro- or nanoseconds. (A nanosecond is the time it takes for light to travel one foot.) This region of unstable elements surrounds the island of stability.

These are unstable elements that die quickly.

A 650.0 mL solution contains 125 grams of glucose (C6H12O6). If the molar mass of C6H12O6 is 180.16 g/mol, what is the molarity

Aleks [24]

Molarity of a solution is the molar concentration, which is the number of moles of solute in 1 L of solution.

the mass of glucose is - 125 g

number of moles of glucose - 125 g / 180.16 g/mol = 0.694 mol

the number of moles of glucose in 650.0 x 10⁻³ L - 0.694 mol

number of moles of glucose in 1 L - 0.694 mol / 650.0 x 10⁻³ L = 1.068 mol/L

molarity of glucose solution is 1.068 M

A Gas OCCUPIES 525ML AT A PRESSURE OF 85.0 kPa WHAT WOULD THE VOLUME OF THE GAS BE AT THE PRESSURE OF 65.0 kPa

Boyle's law of ideal gas: This law states that the volume of a gas is inversely proportional to its pressure at a constant temperature. Acc to this law we can write the relation of pressure and volume as:

$PV=Constant$
