Question

What is the mass of carbon dioxide which contains the
same number of molecules as are contained in 40 g of
oxygen?​

Answer 1

question to acha h answer dene me thoda sa time lagega

Answer 2

molar mass of oxygen = 32 g

means that 32 gram of oxygen contains 1 mole of particles

so 40 gram of Oxygen will contain 40/32 mole of particles =1.25mole of particles

according to the question we have to find now the mass of 1.25 mole of carbon dioxide

molar mass of carbon dioxide=44g

means mass of one mole of carbon dioxide equals 44 gram

therefore mass of 1.25 moles of carbon dioxide equals 44 × 1.25 = 55 g

therefore 55 grams is the mass of carbon dioxide which contains the same number of molecules as contained in 40 gram of oxygen
