Man that is deffinitelly 5,000 mm as 5m=50dm=500sm=5000mm
Answer: M= 128 g/mol (Te is quite close)
Explanation: number of Oxygen moles is n = 8 g / 32 g/mol = 0,25 mol.
Because formula of oxide is MO, thus amount of metal is also 0,25 mol.
Because n = m/M , Molar mass of the metal M = m/n = 32 g /0.25 mol = 128 g/ mol
