What is the molarity of a solution that contains 0.202 mol kcl in 7.98 l solution?

Explanation:

1) Data:

a) M = ?

b) Solute: KCl

c) n = 0.202 mol

d) V = 7.98 liter

2) Principles and formulae:

a) Molarity is the number of moles of solute per liter of solution. The units of molarity are mol/liter, which is equivalent to M.

b) M = n / V (in liter)

3) Solution:

Substitute the data into the equation M = n / V (in liter)

Since the number of moles and the volume are expressed with 3 significant figures, the answer is given with the same number of significant digits.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
