What is hydrogen? Hydrogen is a clean alternative to methane, also known as natural gas. It's the most abundant chemical element, estimated to contribute 75% of the mass of the universe.Here on earth, vast numbers of hydrogen atoms are contained in water, plants, animals and, of course,...
What is the atomic mass of hydrogen?HydrogenHydrogen has three isotopes or different versions of hydrogen. Each of the isotopes has one proton, but different numbers of neutrons. Hydrogen-1 has one proton and zero neutrons. Hydrogen-2 has one proton and one neutron. Hydrogen-3 has one proton...
A small statue that has a mass of 500.0 g displaces 150.5 ml of water. What is its density in grams per millilitres? What is the mass percent of hydrogen in water? What is the mass of NaCl in deionized water? What is the mass of a liquid with a density of 2.12 g/mL and a vol...
A 0.100g sample of carbon-hydrogen-oxygen compound is combusted in a stream of pure oxygen and produces 0.220g CO2 and 0.239g H2O. What is the mass of hydrogen in the sample? If 36 grams of water is split into hydrogen and oxygen g...
- Carbon (C) has an atomic mass of approximately 12 g/mol. - Hydrogen (H) has an atomic mass of approximately 1 g/mol. - Therefore, the molecular mass of CH₄ = 12 + (4 × 1) = 12 + 4 = 16 g/mol. 3. Calculating the number of molecules in 1 kg mole of CH₄: - Ac...

Similarly, hydrogen and oxygen, which are both gaseous elements can combine to form water, which is a liquid compound, not a gas, at room temperature. The process by which such combinations and transformations of elements into compounds take place is called achemical reaction. ...
- The mass 4.35kg has 3 significant figures. - The volume 2.1m3 has 2 significant figures. - According to the rules of significant figures, the final answer should be reported with the least number of significant figures, which is 2 in this case. 5. Round the result to 2 significant fig...

Mass and weight are distinct because weight is a measure of the size of the pull of gravity on the object. So the mass of a rubber ball onEarthwould remain the same onthe moon, but its weight would change because of the reduction in gravitational pull. ...
