You have 100 g of Pb(NO3)2. How many moles is this?

topjm [15]

Answer:

0.302 moles

Explanation:

Data given

Mass of Pb(NO₃)₂ = 100 g

Moles of Pb(NO₃)₂ = ?

Solution:

To find mole we have to know about molar mass of Pb(NO₃)₂

So,

Molar mass of Pb(NO₃)₂ = 207 + 2[14 + 3(16)]

= 207 + 2[14 + 48]

= 207 + 124

Molar mass of Pb(NO₃)₂ = 331 g/mol

Formula used :

no. of moles = mass in grams / molar mass

Put values in above formula

no. of moles = 100 g / 331 g/mol

no. of moles = 0.302 moles

no. of moles of Pb(NO₃)₂ = 0.302 moles
