# calculate the mass of 1 molecule of water

It will calculate the total mass along with the elemental composition and mass of each element in the compound. 18 grams The mass of one mole of any atom/molecule is equal to its atomic molecular mass in grams. Examples: C6H12O6, PO4H2(CH2)12CH3 Calculate molecular mass by: Contact help@bmrb.io if you have any questions about this site 12 + 22 + 11 . How to calculate the mass of a particular isotopic composition. The molecular formula of water is H_2O The atomic mass of H = 1 The atomic mass of O = 16 In a sense, the formula means H + H + O So... 1 + 1 + 16 = 18 Therefore, the mass of one mole of water = 18 Grams Ok, you must know that a water molecule has 2(1) + 16 = 18 protons and neutrons. 1. This program determines the molecular mass of a substance. Mass of one water molecule = 6. 2. molecular mass of sucrose = 12 . Examples: Fe, Au, Co, Br, C, O, N, F. As we know the molecular formula of water is H2O which means that one molecule of water contain 2 atoms of hydrogen and 1 atom of oxygen. Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2. Molecular weight calculation: 1.00794*2 + 15.9994 ›› … The mass of one proton = mass of one neutron = 1.67 * 10^-24 grams, so the mass of 18 n+p = 18*1.67 * 10^-24 grams = 3*10^-23 grams Molar mass of H2O = 18.01528 g/mol. We know that there are two hydrogen atoms and one oxygen atom for every H 2 0 molecule. The density of water is about 1 gram per milliliters (1 g/mL). 0 2 3 × 1 0 2 3 water molecules. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). Use uppercase for the first character in the element and lowercase for the second character. 1 molecule of water = 18 g. No molecules = 18 g. 1molecule = 18 / No . Enter the molecular formula of the molecule. To find the mass of 1.00×10 24 (a septillion) molecules of water, first we have to find the mass of one molecule of water (H 2 O). Therefore, it follows that 1000 mL (one liter) of water will contain 1000 g of water molecules. 16 = 144 + 22 + 176 = 342 g Thus, Molecular Mass Calculator. ›› Water molecular weight. Definitions of molecular mass, molecular weight, molar mass and molar weight. Enter the molecular formula of the substance. Answer: i) Molecular mass of H 2 = 2 x Atomic mass of H = 2 x 1 = 2 u ii) Molecular mass of O 2 = 2 x Atomic mass of O = 2 x 16 = 32 u iii) Molecular mass of Cl 2 = 2 x Atomic mass of Cl = 2 x 35.5 = 71 u iv) Molecular mass of CO 2 = Atomic mass of C + 2 x Atomic mass of O = 12 + 2 x 16 Calculate the mass of one molecule of H 2 ... One mole of water contains 6. Convert grams Water to moles or moles Water to grams. (1 u is equal to 1/12 the mass of one atom of carbon-12) And since the molar mass of water is 18 g per mol (18 g/mol), we can convert the 1000 g of water to moles of water by multiplying 1000 g of water by the ratio (1 mol/18 g).
