The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is amu (2×1.00797 amu for H + 15.9994 amu for O), and a mole of water molecules would weigh 18.02 grams. (amu, g/mol).

At low molar mass, i.e., below some critical molar mass (M c), for flexible chain polymers η 0 depends on M w, while above M c, η 0 depends on M w to the 3.4 to 3.6 power for most flexible linear polymer chains: Similarly, what is the mass of CuSO4 5h2o? 159.609 g/mol . One may also ask, how do you find the percent of water in a hydrate? Divide the mass of the water lost by the mass of hydrate and multiply by 100.

In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. Water (chemical formula: H2O) is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms.

The water has a molecular weight of 18.

Answer: It is 18 g/mol. Explanation: One mole of H2O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of 1 mole of Hydrogen atoms= 1 g /mol Mass of 1mole of Oxygen atoms = 16 g/mol Mass of two moles of Hydrogen atoms = 2x 1

Explanation: One mole of H2O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom.

Answer to Calculate the number of moles of water from the mass of water loss( Mass of water loss equals 0.32 g):(Molar mass of water = 18.0153 g/mol). Then

of water is 18g/mol) hence 1 gram of water contains 1/18 moles So 6 gram water contains (1/18)* (6) i.e. 1/3 moles of water molecules =.333 moles One molar mass of water is equivalent to 18 grams. Therefore, the molar heat capacity becomes the product of 4.186 and 18. It implies that 75.348 Joules of heat energy are needed to raise the temperature of 18 grams of liquid water by one degree Kelvin. 2 S is a gas at room temperature, despite hydrogen sulfide having nearly twice the molar mass of water. The extra bonding between water molecules also gives liquid water a large specific heat capacity. This high heat capacity makes water a good heat storage medium (coolant) and heat shield.

Usually, oxalic acid may be anhydrous (lacking any moisture) or hydrated (water of crystallization is present). Molar mass (M) has a significant effect on the rheological properties of polymer melts and hence on their processing performance. At low molar mass, i.e., below some critical molar mass (M c), for flexible chain polymers η 0 depends on M w, while above M c, η 0 depends on M w to the 3.4 to 3.6 power for most flexible linear polymer chains: The molar mass of a gaseous compound can be determined by experiment even though the formula or composition of the compound is not known. In other words, it is possible to find the molar mass of a gas even if we do not know its identity. The molar mass is determined by using the fact that the number of moles of a gas sample relates to the In this manner, what is the mass percentage of water in copper sulfate? It also means that copper sulfate pentahydrate contains 100 - 63.92 = 36.08 percent water by mass. What is the percentage of water of crystallization in CuSO4 5h2o?
