What is the gram molecular mass of HNO3 is?

What is the gram molecular mass of hydrogen?

The gram molecular mass of hydrogen is 1 gram per mole.

What is the gram molecular mass of a compound if 5 moles of the compound has a mass of 100 grams?

To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.

What is a gram of a molecular substance?

A gram of a molecular substance is the quantity that will have a mass of 1 gram.

The molecular mass of glucose is 180. this means that 180g of glucose contain?

The gram molecular mass of glucose is 180 gram. Reason. The atomicity of glucose is 24.

What is the gram molecular weight of Sodium hydroxide if its molecular mass is 40 a.m.u?

The a.m.u. is defined as the fraction of 1/12 of an atom of the carbon-12 isotope. The value is pretty nearer to the mass of a hydrogen atom. Therefore, in every compound, the gram molecular weight is numerically equal to the molecular mass in atomic mass units. Therefore the gram molecular weight of NaOH is 40 g/mol.

How do you prepare 0.01 M from 65 percent HNO3?

The molar mass of HNO3 is 63 gram/mol and of water is 18 gram/mol. Lets assume that the density of the HNO3 + water mixture is equal to the density of water at room temperature is 1000 gram/L. 0.01 M is equal to 0.01 mol HNO3 per liter HNO3 + water. Multiplying the molar mass of HNO3 by the molarity shows this is equal to 0.63 gram HNO3 per liter HNO3 + water. Using the density of water shows that this is equal to 0.000063 gram HNO3 per gram water. This is therefore 0.0065 percent by weight. (The assumption that the density of the mixture is approximately equal to that of pure water seems justified because the amount of HNO3 in the mixture is very low) Assuming we start with an initial 65 percent by weight of HNO3 (10.3 M using the same type of calculation), water will need to be added to dilute to 0.0065 percent (0.01M). To find the required amount of water that is added a total and component mass balance can be used. The total mass balance is given by: Mt = M0 + Ma Here, M0 is the initial amount of water + HNO3, Ma is the added amount of (pure) water and Mt is the total mass of the water + HNO3 after adding more water. The component mass balance over HNO3 is given by: xtMt = x0M0 + xaMa= x0M0 Where xt is the final weight fraction of HNO3 in water, x0 is the initial weight fraction in water and xa is the weight fraction of HNO3 in pure water (which is logically equal to zero). Lets say we have a starting mass M0 = 100 gram HNO3 + water with the initial weight fraction x0 = 0.65 gram HNO3 per gram and we want a final weight fraction xt = 0.000065, rearranging for the total weight after having added water to reach this dilution gives: Mt = x0M0/xt = 0.65x100/0.000065 = 1000000 gram HNO3 + water The amount of water which needs to be added then simply follows from: Ma = Mt - M0 = 1000000 - 100 = 999900 gram water

What is the gram molecular mass of phosphorous?

The atomic mass of phosphurus is 31. The atomic mass of chlorine is 35.5. Therefore, the gram molecular mass of PCl3 is 31+3x35.5=137.5 grams per mole.

What is gram molecular mass of sulphur?

What is the molecular equation for HNO3 plus KOH?

The molecular equation for the reaction between nitric acid (HNO3) and potassium hydroxide (KOH) is: HNO3 + KOH -> KNO3 + H2O.

What is the gram molecular mass of lithium bromide?

The gram molecular mass of lithium bromide is approximately 86.85 g/mol. This value is obtained by adding the atomic masses of lithium (6.94 g/mol) and bromine (79.90 g/mol).

How do you convert from molecular mass to grams per mole?

Relative molecular mass is obtained by summing up the atomic masses of atoms in the formula. The gram molecular mass denotes the mass of a mole of the substance in grams. Both of them are same in number.
