Question

what is the weight of 1 mole of following
1.nacl
2.caco3

Answer 1

Hi friend,

#Molar mass of Nacl is = 58.44277 g/mol.

This compound is alao known as Sodium chloride.

Convert grams Nacl to Mole :-

Moleculer weight calculation
22.98977 + 35.453

2) Moler mass of Caco3= 100.0869 g/ mole

Convert grams Caco3 to mole ;-

Moleculer weight calculation
40.078 + 12.0107 + 15.9994*3

....i hope it helps you

mark me as a brainlist.

Answer 2

here is your answer.........

remember these formulae =>

n = w/mm = PV /RT = V(in liters) /22.4 =N/Na
where,
n= no. of moles
w= weight of compound
mm= molecular mass of compound
P= pressure
V= volume
R = universal gas constant
N= no. of molecules
Na= Avogadro number= 6.023×10^23

_______________________________
n =1 mole
1. NaCl

mm= 23+35.5= 58.5

n = w /mm
=> w =n× mm
=> w= 58.5 answer

2. CaCO3
n= 1
mm= 40+12+3*16
=52+48
=100
