Question

write down the molecular formula of magnesium carbonate and calculate its molecular weight​

Answer 1

Answer:

a): the molecular formula is Mg(HCO3)2 and molecular mass is 146 g/mol

b): NH4SO2 and moleculr mass is 132.14 g/mol

c): molecular formula is NANO3and molecular mass is 84.99g/mol

d): molecular formula is Al2(SO4)3 and mass is 342.15g/mol

e): molecular formula is NA2SO4 and mass is 142.4g/mol

Explanation:

when magnesium and hydrogen and carobn carbon combine together and make a magnesium by carbonate and aother camicals combine together and made heavy mass.

Answer 2

Answer:

MgCO3

24+12+16×3=86 g/mol

Explanation:
