Answer:
44 98
Explanation:
Carbon Dioxide (CO2) - Has 1 carbon and 2 oxygens,
C=12 O=16,
Relative atomic mass(Ar) = 12 + (16 x 2),
Relative formula mass(Mr)= 44
Sulphuric Acid (H2SO4) - Has 2 hydrogens, 1 sulphur and 4 oxygens,
H=1 S=32 O=16,
Relative atomic mass(Ar) = (1 x 2) + 32 + (16 x 4)
Relative formula mass(Mr)= 98
