The molar mass is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance. The molar mass of atoms of an element is given by the standard relative atomic mass of the element multiplied by the molar mass constant, 1 × 10−3 kg/mol = 1 g/mol.

where ; n = molar flow rate of steam . making n the subject of the formula; we have: Moleular weight of air = 28.84 g/mol. The mass flow rate = molar flowrate × molecular weight of air . Finally: the kinetic energy at Inlet = = 112.164 W . b) If the air is heated to 400°C; Then temperature at 400°C = (400 + 273.15)K = 673.15 K

Molar Mass is the mass of one mole of a substance (6.02 x 1023 formula units). Find the molar mass. 2. Multiply the number of each atom by its atomic weight (found on the Periodic Table of the Elements). HNO3. 63. CCl4.The "molar mass" of any substance indicates the addition of atomic masses of constituent atoms. Hence, to calculate the molar mass, we must know the atomic masses of component atoms.
Explanation: To determine the molar mass of any compound, all you have to do is add up the molar masses of every atom that makes up the respective compound. In this case, you know that ammonia, NH3 , is composed of.

Use MV = mass/molar mass to determine mass of acetic acid present Use that information to calculate the mass percent and mole fraction of HNO3 in the solution.mass=moles x molar mass. Mass in grams = 0.03885 x molar mass of NaCl = 0.03885 x 58.44 = 2.270 grams. b) moles of sodium present in package is 0.03885. mass=moles x molar mass. Mass of sodium will be = 0.03885 x 23=0.89355g. or =893.55 mg. So percent of RDA intake = (893.55 / 904) x 100 = 98.84 %. Explanation: 2) the balanced equation given is
