heres your answer mate...
To tract genetic inheritance ( phenotype or genotype) from one generation to another generation, PEDIGREE CHART is used. Pedigree Chart is a diagram shows the occurrence and appearance of a particular genes of an individual organism from its ancestor down to the generations it follows. Relationship in a pedigree is shown as a series of linear graph. Parents are connected to a horizontal lines while vertical lines will lead to the offspring.
To convert milliliters to liters, you should divide the milliliters by 1000. When we do that here, we will see that there are 0.0456 liters in 45.6 milliliters.
Answer: A compound is a substance made up of a definite proportion of two or more elements. A chemical formula tells us the number of atoms of each element in a compound. It contains the symbols of the atoms of the elements present in the compound as well as how many there are for each element in the form of subscripts.

Answer is: concentration of the sodium hydroxide solution is 2M.
Balanced chemical reaction:
3NaOH(aq) + Cr(NO₃)₃(aq) → Cr(OH)₃(s) + 3NaNO₃(aq).
m(Cr(OH)₃) = 2.06 g.
n(Cr(OH)₃) =2.06 g ÷ 103 g/mol.
n(Cr(OH)₃) = 0.02 mol.
From reaction: n(Cr(OH)₃) : n(NaOH) = 1 : 3.
n(NaOH) = 0.06 mol.
From chemical reaction: NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l):
n(HCl) = n(NaOH) = 0.1 L · 0.4 M = 0.04 mol.
n(NaOH) = 0.06 mol + 0.04 mol = 0.1 mol.
c(NaOH) = 0.1 mol ÷ 0.05 L = 2 mol/L.
