In this experiment it takes in this experiment it takes about 10 microliters of solution to produce a spot 1 cm in diameter. if the co(no3)2 solution contains about 6 g co^2+ per liter, how many micrograms of co^2+ ion are there in one spot

60 micrograms( μg) of Co²⁺ ions are there in one spot

7 main quantities have been determined based on international standards, namely:

Mass is one of the principal quantities, which is related to the matter in the object

The main mass unit consists of 7 units of other than other units of mass such as quintals, tons, pounds, ounces:

Kilogram, kg

Hectogram, hg

Decagram, dag

gram, g

Decigram, dg

centigram, cg

milligrams, mg

Each unit descends then multiplied by 10, and if one unit increases then divided by 10

Conversion of other mass units:

mg milligrams = 10⁻³ g

kg kilograms = 10³ g

µg micrograms (mcg) = 10⁻⁶ g

Mg megagrams (tons) = 10 g

ng nanograms = 10⁻⁹ g

Gg gigagram = 10⁹ g

 g picogram = 10⁻¹² g

The volume itself is a derivative of length with a standard unit of m³

Volume is the amount of how much space an object has

The basic units of the volume include:

1 m³ = 10³ dm³ = 106 cm³

1 dm³ = 1 L

1 cm³ = 1 ml

1μL = 10⁻⁶ L

Co(NO₃)₂ solution contains about 6 g Co²⁺ per liter, then in μg it becomes:

6 g/L x 10⁶ = 6.10⁶ μg / L

We change to μL to:

6.10⁶ μg / L x 1 L / 10⁶ μL = 6 μg / μL

So in Co(NO₃)₂ solution there are 6  μg / μL  Co²⁺ ions

Because it takes 10 μL  (microliters) of solution to produce a spot of 1 cm, then the amount of Co²⁺ ions are there in one spot

6 μg / μL x 10 μL = 60 μg
