how do we calculate one revolution?

Let, The mass of the organic compound taken be = W g Volume of air displaced = V 1 mL Atmospheric pressure = P mm of Hg Room temperature, T 1 = t o C = (t + 273)K Aqueous tension at t o C = p mm of Hg Pressure of the dry air, P 1 = (P-p) mm Hg ..

Let, The mass of the organic compound be = W g Mass of the precipitate of BaSO 4 = W 1 g From stoichiometry, BaSO 4 = S 1 mol 1 mol 1 molecular mass 1 atomic mass 233 g 32 g Therefore, ..

Let, The mass of the organic compound taken be = W g Volume of nitrogen collected = V 1 g Atmospheric pressure = P mm Hg Temperature at which gas is collected = T 1 K Therefore, Pressure of the N 2 gas, P 1 = (P - p) mm of Hg..

Let, The mass of the organic compound taken be = W g Increase in the mass of magnesium perchlorate tube = W 1 g Increase in the mass of the KOH tube = W 2 g So, Mass of water formed = W 1 g Mass of carbon dioxide formed = W 2 g ..

Let, Mass of the organic compound = W g Volume of the standard acid required for complete neutralization of the evolved ammonia = V mL Normality of the standard solution of acid = N From the law of equivalence (normality equation), 1000 mL of 1 N acid = 1000 mL of 1 N NH 3 = ..

Consider an ideal gas enclosed in a cubical vessel of edge L. Take a corner of the vessel as the origin O and the X-,Y-, Z- axes along the edges (figure 1). Let A1 and A2 be the parallel faces, perpendicular to the X-axi..

A road-roller levels 75.5 yards in 5 revolutions. Find the length of the road leveled in one revolution. => 20.1 yards or 17.1 yards or 10.1 yards or 15.1 yards..

Molecular mass is equal to sum of the atomic masses of all atoms present in one molecule of the substance. Example: H 2 O Mass of H atom = 1 Mass of 2H atoms = 2 Mass of O atom = 16 Molecular mass = 2 + 16 = 18..

The mass of an electron (m) is determined by dividing the value of 'e' by e/m. Charge/mass (e/m) = 1.76 x 10 8 coulomb/g Charge (e) = 1.602 x 10 - 1 9 coulombs...

The average rate of reaction is calculated by determining the difference in [O 2 ] concentration over different intervals of time and dividing the difference by D ..
