To determine the molar mass of the unknown gas, we use Graham's Law of Effusion where it relates the effusion rates of two gases with their molar masses. It is expressed as r1/r2 = √M2/M1. We calculate as follows:
Let 1 = argon gas 2 = unknown gas
r2 = 0.91r1r1/r2 = 1/0.91
1/0.91 = √M2/M1 = √M2/40M2 = 48.30 g/mol
Answer:
<h3>An acid that contains more than one ionizable proton is a polyprotic acid. The protons of these acids ionize in steps. The differences in the acid ionization constants for the successive ionizations of the protons in a polyprotic acid usually vary by roughly five orders of magnitude.</h3>
Answer: Calculate the molar mass of Mg3(PO4)2 in grams per mole or search for a chemical formula or substance.
Missing: 643.21 Must include: 643.21. A balloon is filled with 36.2 liters of Cl2 gas at STP. How many moles of chlorine gas are inside? Solution: 36.2
Missing: 4.061 Must include: 4.061 .For H2O, there is one atom of oxygen and two atoms of hydrogen. A molecule can be made of only one type of atom. In its stable molecular form, oxygen exists as two atoms and is written O2. to distinguish it from an atom of oxygen molecule of three oxygen atoms, in grams per mole or search for a chemical ... Did you mean to find the molecular weight of one of these similar formulas- 80.34.
