Question

which has more number of atoms 100gm of aluminium or 100gm of oxygen​

Answer 1

Answer:

oxygen have more atoms than alumminum

Answer 2

Answer:

100 grams

Explanation:

Atomic mass of Na = 23 u

Atomic mass of Na = 23 uAtomic mass of Fe = 56 u

Atomic mass of Na = 23 uAtomic mass of Fe = 56 uThen, gram atomic mass of Na = 23 g

Atomic mass of Na = 23 uAtomic mass of Fe = 56 uThen, gram atomic mass of Na = 23 gNow, 23 g of Na contains = 6.022 x 1023 g number of atoms

Atomic mass of Na = 23 uAtomic mass of Fe = 56 uThen, gram atomic mass of Na = 23 gNow, 23 g of Na contains = 6.022 x 1023 g number of atomsThus, 100 g of Na contains = 6.022 x 1023 / (23 x 100 number of atoms)

Atomic mass of Na = 23 uAtomic mass of Fe = 56 uThen, gram atomic mass of Na = 23 gNow, 23 g of Na contains = 6.022 x 1023 g number of atomsThus, 100 g of Na contains = 6.022 x 1023 / (23 x 100 number of atoms) 100 g of Na contains = 2.6182 x 1024 number of atoms

Atomic mass of Na = 23 uAtomic mass of Fe = 56 uThen, gram atomic mass of Na = 23 gNow, 23 g of Na contains = 6.022 x 1023 g number of atomsThus, 100 g of Na contains = 6.022 x 1023 / (23 x 100 number of atoms) 100 g of Na contains = 2.6182 x 1024 number of atomsThen, gram atomic mass of Fe = 56 g

Atomic mass of Na = 23 uAtomic mass of Fe = 56 uThen, gram atomic mass of Na = 23 gNow, 23 g of Na contains = 6.022 x 1023 g number of atomsThus, 100 g of Na contains = 6.022 x 1023 / (23 x 100 number of atoms) 100 g of Na contains = 2.6182 x 1024 number of atomsThen, gram atomic mass of Fe = 56 gNow, 56 g of Fe contains = 6.022 x 1023 g number of atoms

Atomic mass of Na = 23 uAtomic mass of Fe = 56 uThen, gram atomic mass of Na = 23 gNow, 23 g of Na contains = 6.022 x 1023 g number of atomsThus, 100 g of Na contains = 6.022 x 1023 / (23 x 100 number of atoms) 100 g of Na contains = 2.6182 x 1024 number of atomsThen, gram atomic mass of Fe = 56 gNow, 56 g of Fe contains = 6.022 x 1023 g number of atomsThus, 100 g of Fe contains = 6.022 x 1023 / (56 x 100 number of atoms)

Atomic mass of Na = 23 uAtomic mass of Fe = 56 uThen, gram atomic mass of Na = 23 gNow, 23 g of Na contains = 6.022 x 1023 g number of atomsThus, 100 g of Na contains = 6.022 x 1023 / (23 x 100 number of atoms) 100 g of Na contains = 2.6182 x 1024 number of atomsThen, gram atomic mass of Fe = 56 gNow, 56 g of Fe contains = 6.022 x 1023 g number of atomsThus, 100 g of Fe contains = 6.022 x 1023 / (56 x 100 number of atoms)100 g of Fe contains = 1.0753 x 1024 number of atoms

Atomic mass of Na = 23 uAtomic mass of Fe = 56 uThen, gram atomic mass of Na = 23 gNow, 23 g of Na contains = 6.022 x 1023 g number of atomsThus, 100 g of Na contains = 6.022 x 1023 / (23 x 100 number of atoms) 100 g of Na contains = 2.6182 x 1024 number of atomsThen, gram atomic mass of Fe = 56 gNow, 56 g of Fe contains = 6.022 x 1023 g number of atomsThus, 100 g of Fe contains = 6.022 x 1023 / (56 x 100 number of atoms)100 g of Fe contains = 1.0753 x 1024 number of atomsTherefore, 100 grams of sodium contains more number of atoms than 100 grams of iron.
