Answer to Question #176531 in General Chemistry for Joshua Jarkar

Question

How many mole of particles are contained in 34gram of NH3(formula mass 17gram per mole

Answer 1

Mass=34g

Molar mass=17g/mol

Mole=mass/molar mass

=34/17=2moles

Now,

Mole= number of particles/Avogadro's number

Number of particles= mole x Avogadro's number= 2 x 6.02x10²³= 1.204x10²⁴
