1 answer:

6 0

Accordingly, the majority of the bonds in the molecule, tin (ii) sulfide, are covalent, accounting for around 90% of the bonds. An extremely thin anode interlayer is used in organic photovoltaics by the compound tin(II) thiocyanate, Sn(SCN)2.

Stannic sulfide, tin disulfide, and tin bis(sulfanylidene) are examples. EC number: 215-252-9; CAS number: 1315-01-1. A chemical compound is tin(II) sulfate. SnSO4 is its atomic number. Tin and sulfate ions can be found in it. The chemical element tin has the atomic number 50 and the letter Sn for its symbol. At room temperature, tin is solid and is categorized as a post-transition metal. In order to create Tin dioxide and two molecules of hydrogen gas, Tin combines with two molecules of water, which are really in the form of steam. A reminder: Acids and alkalis corrode tin.

How many moles are there in 44.71 g of chlorine (cl)? use significant figures?

krok68 [10]

Mass of chlorine = $44.71 g$ (given)

Molar mass of chlorine = $35.45 g/mol$

Now, number of moles is defined as the ratio of given mass in gram to the molar mass of the compound.

Number of moles = $\frac{given mass in g}{molar mass}$

Number of moles of chlorine = $\frac{44.71 g}{35.45 g/mol}$

= $1.26121297 moles$

Now, according to significant figure rules, the least number of significant figure in the question identifies the number of significant figures in the solution.

Thus, in question, both digit have four significant figures, therefore, the answer must be in four significant figures.

Hence, number of moles of chlorine = $1.261 moles$
