What mass of nano3 is needed to make 3.5 l of 2.2 m solution? (na = 23.0g, n=14.0g, o=16.0g)
explain in steps

= 654.5 g NaNO3

Explanation:

Molarity = Moles/ volume

Volume = 3.5 L

Molarity = 2.2 M

Therefore;

Moles = Molarity × volume

          = 3.5 L × 2.2 M

          = 7.7 moles

But 1 mole of NaNO3 is 85 g/mol

Mass of NaNO3 = 85 g/mole × 7.7 moles

                          = 654.5 g NaNO3

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
