love history [14]

T_1=27°C
T_2=40°C
V_1=1L
V_2=?

Using Charles law

$\boxed{\sf \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}}$

$\\ \sf\longmapsto V_1T_2=V_2T_1$

$\\ \sf\longmapsto 1(40)=27V_2$

$\\ \sf\longmapsto V_2=\dfrac{40}{27}$

$\\ \sf\longmapsto V_2=1.48\ell$

A 20.38 gram sample of cobalt is heated in the presence of excess sulfur. A metal sulfide is formed with a mass of 31.47 g. Dete

Viefleur [7K]

Answer: The empirical formula of the metal sulfide is $CoBr_{2}$ .

Explanation:

Given: Mass of metal = 20.38 g

Mass of metal sulfide = 31.47 g

Moles is the mass of a substance divided by its molar mass.

So, moles of cobalt (molar mass = 59 g/mol) are as follows.

$Moles = \frac{mass}{molarmass}\\= \frac{20.38 g}{59 g/mol}\\= 0.345 mol$

Moles of bromine (molar mass = 80 g/mol) are as follows.

$Moles = \frac{(31.47 - 20.38) g}{80 g/mol}\\= \frac{11.09 g}{80 g/mol}\\= 0.138 mol$

Now, the ratio of number of moles of cobalt and number of moles of bromine are as follows.

Moles of Co : Moles of Br = 1 : 2

Hence, the empirical formula is $CoBr_{2}$ .

Thus, we can conclude that the empirical formula of the metal sulfide is $CoBr_{2}$ .
