How many grams of P2Cl5 are produced if 2.00 moles of P reacts with an excess of Cl2?

Roman55 [17]

Answer:

$m_{P_2Cl_5 }=239.2125gP_2Cl_5$

Explanation:

Hello there!

In this case, according to the reaction:

$4P+5Cl_2\rightarrow 2P_2Cl_5$

Thus, since there is a 4:2 mole ratio of P to P2Cl5 and the molar mass of the later is 239.2125 g/mol, we obtain the following mass as the produced one:

$m_{P_2Cl_5 }=2.00molP*\frac{2molP_2Cl_5}{4molP} *\frac{239.2125gP_2Cl_5 }{1molP_2Cl_5} \\\\m_{P_2Cl_5 }=239.2125gP_2Cl_5$

Question 2 of 10 A chemist has a block of copper metal (density is 8.96 g/mL). They drop the metal into a graduated cylinder con

Paladinen [302]

Answer:

m = 25.98 g

Explanation:

Given data:

Density of copper metal = 8.96 g/mL

Volume of copper metal block = 2.90 mL

Mass of copper metal block = ?

Solution:

The volume of given block of copper is equal to the volume change of water by adding this block.

Density formula:

d = m/v

by putting values,

8.96 g/mL = m/ 2.90 mL

m = 8.96 g/mL × 2.90 mL

m = 25.98 g
