Question

find the molar mass of 1) MgSo4 1) c6h12o6

Answer 1

1. Molar Mass of MgSo4

Atomic Masses - Mg- 24.31, S- 32.07, O- 16.00

add up the masses of all atoms-
24.31+32.07+16*4= 120.36 g/ mol

Molar Mass of MgSo4 = 120.36 g/ mol

2. Molar Mass of C6H12O6
Atomic Masses = C- 12.0107, H-1.00794, O-16.00

add up the masses of all atoms-
12.0107*6 + 1.00794*12 + 15.9994*6
=180.15588 g/mol

¶ Calculating Molar Mass of a Compound:
- Add the Atomic masses of Individual elements multiplied by number of atoms.
- And is expressed in terms of g/mol

¶¶¶ Answer:

1) $MgSO_{4}$ contains elements :
Mg, S, O
Atomic Mass of Mg= 24.31
Atomic Mass of S =32.07
Atomic Mass of O = 16

Molar Mass of $MgSO_{4}$
= $M_{Mg}+M_{S}+4M_{O}$
= 24.31 + 32.07 + 4(16)
= 120.38 g/mol

2)

$C_{6}H_{12}O_{6}$ contains elements :
C, H , O

Atomic Mass of C = 12.01
Atomic Mass of H = 1.00
Atomic Mass of O = 16.00

Molar Mass of $C_{6}H_{12}O_{6}$
= $6M_{C}+12M_{H}+6M_{O}$
= 6(12.01) + 12(1) + 6(16)
= 180.06 g/mol
