please mark as brainliest answer
Answer:
for ammonium hydroxide ( (NH4)2CO3 ) 96 gm/mol
Molecular mass of potassium carbonate (K2CO3) is 138gm/mole
Explanation:
The molecular mass of (NH4)2CO3 is :
Given atomic mass of H = 1, O = 16, C = 12, N = 14.
Molar mass(MolecularMass) of (NH4)2CO3 is :
molecular mass of NH4 is atomic wgt of N+atomic wgt of 4 Hydrogens is 14+4 =18
and (NH4)2 is 18x2 = 36 gm/mole
molecular mass of CO3 is atomic wgt of C(carbon) + atomic wgt of 3 O(oxygen atoms)
is : 12+ 3x(16)
= 12+48
=60 gm/mole
The total molecular mass of ammonium hydroxide is sum of molecular mass of (NH4)2 and CO3
=2×18+60
=36+60
=96gm/mole
The molar mass of Potassium Carbonate is K2CO3 = 39(2)+12+16(3)
K2CO3 = 78+12+48 K2CO3 = 138 g/mol.
Follow the same procedure above we did.
