What else can I help you with?
The formula mass of a molecule or an ion is?
The formula mass of a molecule or an ion is the sum of the atomic masses of all the atoms in the formula unit. This value is expressed in atomic mass units (amu) and is used to calculate the molar mass of the compound.
Where does most of the mass of glucose come from?
Most of the mass of glucose comes from carbon atoms, which are incorporated into the glucose molecule during photosynthesis. Carbon dioxide is taken in from the air during photosynthesis and converted into glucose, providing the majority of its mass.
What is the atomic mass of starch?
The atomic mass of a starch molecule is calculated by adding up the atomic masses of all the atoms it contains. Since starch is composed of carbon, hydrogen, and oxygen atoms, the atomic mass can vary depending on the specific ratio of these atoms in the molecule. The average molecular weight of starch is around 162 grams per mole.
How many atoms of carbon are present in 18g of glucose?
glucose 1 mole has 180,156 grams and has 6.022 x 1023 atoms carbon 1 mole has 12,01 grams and has 6.022 x 1023 atoms. There are 6 carbon atoms in a glucose molecule so that times six would give you a total of 72,06 grams out of the 180,156. Carbon makes up about 40 percent of the total glucose mass so the final answer would be it would be around 2.4088 x 1023 atoms of carbon in one gram of glucose.
Can Atomic mass be used to determine molecular mass?
Yes, the accumulation of atomic masses of the atoms within a molecule is the molecule's molecular mass.
What percent by mass of each chloroform molecule is composed of carbon?
Each chloroform molecule (CHCl3) is composed of 12.5% carbon by mass. Carbon has a molar mass of 12.01 g/mol and accounts for one out of the four atoms in each chloroform molecule.
How many atoms of carbon are in 2.50 grams of theobromine C7H8N4O2?
To calculate the number of carbon atoms in 2.50 grams of theobromine (C7H8N4O2), you first need to find the molar mass of theobromine. The molar mass of theobromine is 180.16 g/mol. From the molecular formula, there are 7 carbon atoms in one molecule of theobromine. Therefore, using the molar mass and the number of carbon atoms in the molecule, you can calculate the number of carbon atoms in 2.50 grams.
Whast is the mass number of carbon dioxide?
Carbon is a metal element. Atomic mass number of it is 12.
What is the total mass of the carbon in 2 molecules of butane?
4 Carbon atoms in one molecule of Butane, times 2 because of two molecules, time the weight of one Carbon atom, which is 12 amu's (an amu = atomic mass unit, also known as a Dalton) equals 96 amu's.
What is the mass of a carbon dioxide molecule?
44.010 g/mol You can sum up atomic weight of 1 carbon and 2 oxygen to this figure.
How many Helium-atoms and Carbon-atoms do you have if you have He-atoms with mass of 40amu and C-atoms with mass of 120amu?
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms
Can a molecule contain as few as two atoms or more than a million atoms?
Yes - both. A molecule may contain as few as two atoms - e.g. CO carbon monoxide or greater than a million atoms e.g. Ultra High Mass Polyethylene.
The average relative mass of an ozone molecule is 48.0 you. An ozone molecule contains only oxygen atoms. What does this molecular weight indicate about the formula of the ozone molecule?
The molecular weight of ozone indicates that an ozone molecule consists of three oxygen atoms. This is because the relative atomic mass of oxygen is approximately 16 u, and three oxygen atoms (16 + 16 + 16 = 48 u) combine to form an ozone molecule with a molecular weight of 48.0 u.
The formula mass of a molecule or an ion is?
The formula mass of a molecule or an ion is the sum of the atomic masses of all the atoms in the formula unit. This value is expressed in atomic mass units (amu) and is used to calculate the molar mass of the compound.
What is the molecular mass of substance each molecule of which contain 4 carbon atoms and 10 hydrogen atoms.?
This would be C4H10 and the molecular mass is (12x4) +(1x10) = 48 + 10 = 58g/mole.
Where does most of the mass of glucose come from?
Most of the mass of glucose comes from carbon atoms, which are incorporated into the glucose molecule during photosynthesis. Carbon dioxide is taken in from the air during photosynthesis and converted into glucose, providing the majority of its mass.
