What gives you the most information a molecular or a structural formula?
through their hydrogen carbon
What is the atomic mass of water?
The relative atomic mass of hydrogen is 1 and for oxygen it's 16. This gives water (which has the formula H2O) a molecular mass of 18.
What is the molecular mass of vitamin K C31H46O2?
Atomic mass for carbon,hydrogen and oxygen are 12,1 and 16 respectively.since the molecular formula of vitamin K is C31H46O2, then the respective atomic mass for each element are substituted in the molecular formula. That is,the total number of carbon present is 12 multiplied by 31 which gives 372,the total number of hydrogen present is 1 multiplied by 46 which gives 46,and finally the total number of oxygen present is 16 multiplied by 2 which gives 32.The total addition of all these gives the molecular mass 450g. answer 450.7
What occurs when Hydrogen is turned into helium?
The result of this separation will be pure hydrogen and pure helium.
What is the molecular formula of a compound that has a molecular mass of 54 and the empirical formula C2H3?
C4H6. C2H3 gives a molecular mass of 27, 54/27 gives 2. Therefore the molecular formula is twice the empirical formula.
What gives you the most information a molecular or a structural formula?
through their hydrogen carbon
What atoms does each molecule h2o contain?
two hydrogen and 1 oxygen, the chemical formula is H2O which gives you the answer
What atom does each molecule of H2O contain?
two hydrogen and 1 oxygen, the chemical formula is H2O which gives you the answer
What is the formula for potassium plus water yields potassium hydroxide plus hydrogen?
2H+2H2O gives 2KOH+H2
Combustion analysis of toluene a common organic solvent gives 5.86 mg of CO2 and 1.37 mg of H2O If the compound contains only carbon and hydrogen what is its empirical formula?
The empirical formula is CH2
What is the atomic mass of water?
The relative atomic mass of hydrogen is 1 and for oxygen it's 16. This gives water (which has the formula H2O) a molecular mass of 18.
What does a structural formula depict that a molecular formula does not?
Structural formulas show a representation of the molecular structure, while chemical formulas do not. This is especially important when multiple compounds have the same chemical formula, but a different molecular structure.
How many hydrogen atoms are there in an alkane molecule with 10 carbon atoms?
Formula for alkanes:Number of H = 2 * number of C + 2So, using this formula, H = 2 * 10 + 2, which gives 22
What is the empirical formula of C4H6?
The empirical formula of organic compounds is the lowest whole number ratio of atoms contained in the substance, as defined in chemistry. The empirical formula gives the minimal ratio of the number of various atoms that exist. It's an empirical formula, if the formula is shortened, but not the exact number of atoms in the molecule, C4H6 is the chemical formula for butane. For every mole of carbon, there are two moles of hydrogen. The carbon-to-hydrogen ratio equals 2:3. C2H3 is the empirical formula for butane (C4H6). Hence, the correct answer is C2H3.
When aluminum metal is added to hydrobromic acid what kind of change occurs?
it gives us a new substance that is aluminum bromide therefore it is a chemical change.
What is the molecular mass of vitamin K C31H46O2?
Atomic mass for carbon,hydrogen and oxygen are 12,1 and 16 respectively.since the molecular formula of vitamin K is C31H46O2, then the respective atomic mass for each element are substituted in the molecular formula. That is,the total number of carbon present is 12 multiplied by 31 which gives 372,the total number of hydrogen present is 1 multiplied by 46 which gives 46,and finally the total number of oxygen present is 16 multiplied by 2 which gives 32.The total addition of all these gives the molecular mass 450g. answer 450.7
What force of attraction gives rise to the -helix?
hydrogen bonding
