GPT 3.5
The molar mass of gallium (Ga) is approximately 69.723 g/mol.
Number of moles = Mass / Molar mass
Number of moles = 32.0 g / 69.723 g/mol
Number of moles = 0.459 moles
Therefore, the chemist weighed out approximately 0.459 moles of gallium.
Number of moles = Mass / Molar mass
Number of moles = 32.0 g / 69.723 g/mol
Number of moles = 0.459 moles
Therefore, the chemist weighed out approximately 0.459 moles of gallium.
