Is there a molar mass of 4.0 PH buffer?
Ph gives the hint about the proton gradient of the solution as pH=-log[H+] we need the inforamtion of the molecular composition of the solution to know about the molar mass. Ph gives the hint about the proton gradient of the solution as pH=-log[H+] we need the inforamtion of the molecular composition of the solution to know about the molar mass.
What is the molar mass of fenugreek?
The molar mass of fenugreek (C6H4O3) can be calculated by summing the atomic masses of each element: (C: 12.01 g/mol) + (H: 1.01 g/mol) + (O: 16.00 g/mol) x 3. This gives a molar mass of fenugreek of approximately 180.16 g/mol.
How do you find the molar mass of compounds like water?
The molar mass is the mass of one mole of a substance in g/mol. In order to determine the molar mass, you must know the chemical formula and have access to a periodic table. Let's use water as an example. The chemical formula for water is H2O. To find the molar mass, multiply the atomic weight on the periodic table in grams/mol for each element times the subscript for the element, and add the molar masses. H: 2 x 1.00794g/mol = 2.01588g/mol O: 1 x 15.9994g/mol = 15.9994g/mol ------------------------------------------------ Molar mass = 18.0153g/mol
The formula for benzene is C6H6. Figure the molar mass of benzene to the nearest gram.?
The molar mass of benzene is 78 g.
What is the molecular formula of a substance that decomposes into 1.33 g of H and 21.3 g of O and was found to have a molar mass of 34.1 g?
h2O2
Molar mass of estrogen?
the molar mass of estrogen is 272.42 g/mol C- 18x12.01 H- 24x1.01 O- 2x16
Mass of a mole?
The molar mass of an element is its atomic weight in grams. The molar mass of a molecule or compound is the sum of the subscripts times the molar masses in grams. For example, the molar mass of hydrogen, H, is 1.00794g and the molar mass of oxygen, O, is 15.9994g. The molar mass of water, H2O, is (2 x 1.00794g) + (1 x 15.9994g O) = 18.01528g.
What is the molar mass of C4H8O4?
To determine the molar mass of a molecule, you need to determine the molar mass of each element from the periodic table, then multiply the molar mass by the subscript for the element in the formula. Do this for all of the elements in the formula and add them together to get the molar mass. The molar mass of an individual element is its atomic weight in grams. Molecular molar mass of C4H8O4 = (4 atoms C x 12.0107g/mol C) + (8 atoms H x 1.00794g/mol H) + (4 atoms O x 15.9994g/mol O) = 120.1039g/mol C4H8O4
How many moles are in hydrogen atoms?
divide the mass of the hydrogen by the molar mass.
What is the molecular formula of the compound CH2 with molar mass equals 168?
1. CH2 is the chemical formula of the radical methylene. The structure is H-C-H. 2. The molar mass of CH2 is approx. 14; 168 is an error.
How many moles of hydrogen are in 6.50 g of ammonia?

What is the molar mass of ammonium chloride?
The molar mass of ammonium chloride is 53.5 g/mol.
What is the molar mass of a PVA?
Molar mass is 44. Linear Formula of PVA is [-CH2CHOH-]n. As C=12 O=16 H=01 Hence (12+2+12+1+16+1=44)
What is the molar mass of (NH4)2SO4?
Using estimated atomic wts...For N: 2x14 = 28For H: 8x1 = 8For S: 1x32 = 32For O: 4x16 = 64Total = 132 g/mole = molar mass
What is the molar mass of fenugreek?
The molar mass of fenugreek (C6H4O3) can be calculated by summing the atomic masses of each element: (C: 12.01 g/mol) + (H: 1.01 g/mol) + (O: 16.00 g/mol) x 3. This gives a molar mass of fenugreek of approximately 180.16 g/mol.
What is the molar mass of KOH?
molar mass is the mass of one mole of a substance. A mole is an amount, refers to Avogadros number which is 6.022 x 1023. a mole of atoms is that many atoms. therefore the molar mass of potassium hydroxide KOH is the mass of that many molecules of KOH. On the periodic table the mass number for each element is molar, so all you need to do is add together the molar mass of each element in the compound. Molar mass of potassium (K) is 39 Molar mass of oxygen (O) is 16 Molar mass of hydrogen (H) is 1 There is one of each of these elements in a molecule of potassium hydroxide therefore the molar mass = 39 + 16 + 1 = 56
