find out the mass ratio of a.water b.ammonia c.carbon dioxide
Answers
Answer:
water
Ratios of Mass As the water molecule has exactly two elements, you can use the numbers already calculated to determine the ratios of mass. For example, to find the ratio of mass of hydrogen to oxygen in water, divide the total molar mass of hydrogen, 2.016, by the molar mass of oxygen, 16.00 and get 0.126.
ammonia
Mass Balance Problem. The balanced equation for the synthesis of ammonia is 3 H 2(g) + N 2(g) → 2 NH 3(g). Calculate: The mass in grams of NH 3 formed from the reaction of 64.0 g of N 2. The mass in grams of N 2 required for form 1.00 kg of NH 3.
carbon dioxide
Carbon dioxide always has 2.67 g of oxygen for every gram of carbon. Calculating mass ratios is easy enough if you have access to a periodic table (see Resources) and the means to do basic algebra. Say you want to calculate the mass ratio of sulfuric acid, H 2SO 4.

Answer:
I can tell only first option answer ok. .... the mass percent of hydrogen in water (H20) divide the molar mass of hydrogen by molar mass of water and multiply the result by 100...
