Answer :
33g
explanation
n=mM
Where:
- n is the amount or number of moles
- m is the mass in grams
- M is the molar mass in grams/mole
n=0.75
Calculate molar mass by adding the atomic masses of all atoms in the molecule
M=12+16⋅2
=44
m=n⋅M
=0.75⋅44
=33g
Answer:
4.5 ×10^22)
Explanation:
no. of particles =no. of mole×avogadro's number of particles no. of particles =0.75×6.02×10^23 no. of particles =4.5 ×10^22
