Answer:

Number of moles = 2.2 mol

Explanation:

Given data:

Number of moles of lead = ?

Mass of lead = 456 g

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of lead = 207.1 g/mol

Now we will put the values in formula:

Number of moles = 456 g/ 207.1 g/mol

Number of moles = 2.2 mol

solution:

$the reaction for formation of methyl acetate is\\CH_{3}OH+CH_{3}COOH----------->CH_{3}COOCH_{3}+H_{2}O\\standard internal energy \\\delta u=\delta H -\delta(pv)=\delta H -\delta n\times RT\\where \delta n=change in number of moles=0\\\delta u=\delta H\\=-442kj/mol$
