Explanation: The atomic mass of iron (Fe) is 55.85 amu. The atomic mass of radium (Ra) is 226 amu. One mole of atoms of any element contains 6.022 X 1023 atoms, regardless of the type of element. The mass of one mole of an element depends on what that element is, and is equal to the atom mass of that element in grams.
I think the answer is 10g
when you freeze a specific amount of water into an ice cube, only the form and the density is changed, while the mass will be pretty much the same.
Probably the mass of the melted water will be a little bit less than the cube (if count the mass that released to the air) , but the amount will NOT BE SIGNIFICANT.
Answer:
Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat. Hydrocarbons are molecules consisting of both hydrogen and carbon. ... Methane combining with 2 oxygen to form carbon dioxide, water and heat.
water acts as the solvent for this experiment
we use to calculate R f values and compare with know to determine the compound is made of example in forensic science to find DNA, amino acids
