Answer 1

Answer #1

Look at it from moles only.
how many moles of O2 is in 5.2grams?
mole=5.2/32 work this precisely.
YOU will get twice this moles of product. What is the mass?
Moles product: 5.2/32 * 2

so what is the mass of the product:
massD2O= 5/32 *2*molmassD2O
massH2O=5/32 * 2 * molmassH2O
