Question

A new compound G₇K₂H₄ contained a new element G, gregium. Gregium has an atomic weight of 313.10 g/mol. What is the molecular weight of the new compound?

Answer 1

The molecular weight of the compound
`G_7K_2H_4`lculated by multiplying the atomic weight of each element by its number in the molecule and summing these values, resulting in 2273.94 g/mol.

Step-by-step explanation:

To calculate the molecular weight of the new compound
`G_7K_2H_4`, we need to consider the molecular weights of each component element and their quantities in the molecule. The atomic weight of gregium (G) is given as 313.10 g/mol. The atomic weight of potassium (K) is a standard value of approximately 39.10 g/mol, and for hydrogen (H), it is approximately 1.01 g/mol. To calculate the molecular weight of
`G_7K_2H_4`, you multiply the atomic weight of each element by the number of atoms of that element in the molecule and then sum the total

The molecular weight of the compound is: (7 × 313.10 g/mol) + (2 × 39.10 g/mol) + (4 × 1.01 g/mol) = 2191.7 g/mol + 78.2 g/mol + 4.04 g/mol = 2273.94 g/mol.
