Which molecule is largest? hydrogen carbon dioxide ammonia maltose

maltose

Explanation:

If we intend to determine the largest molecule, then we must look at the relative molecular mass of each molecule because the larger the molar mass, the larger the molecule.

Hydrogen =2 gmol-1

Carbon dioxide = 44 gmol-1

Ammonia = 17 gmol-1

Maltose= 342.3 g/mol

Hence maltose is the largest molecule among the options.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
