The moles of potassium atoms in a 50.0 g sample the mass of mg in a 1.82 mole sample chapter 3 moles x = grams grams 1 mol grams x = moles 1 mol grams molar conversions determine the following: the moles of fecl 3 in a 50.0 g sample the mass of mgcl 2 in a 2.75 mole sample chapter 3. Because the definitions of both the mole and the atomic mass unit are based on the same reference substance, 12 c, the molar mass of any substance is numerically equivalent to its atomic or formula weight in amu.per the amu definition, a single 12 c atom weighs 12 amu (its atomic mass is 12 amu). according to the definition of the mole, 12 g of 12 c contains 1 mole of 12 c atoms (its molar. Mount mazama (giiwas in the native american language klamath) is a complex volcano in the state of oregon, united states, in a segment of the cascade volcanic arc and cascade range.most of the mountain collapsed following a major eruption approximately 7,700 years ago. the volcano is in klamath county, in the southern cascades, 60 miles (97 km) north of the oregon–california border..
Physical properties. sulfur forms several polyatomic molecules. the best-known allotrope is octasulfur, cyclo-s 8.the point group of cyclo-s 8 is d 4d and its dipole moment is 0 d. octasulfur is a soft, bright-yellow solid that is odorless, but impure samples have an odor similar to that of matches. it melts at 115.21 °c (239.38 °f), boils at 444.6 °c (832.3 °f) and sublimes more or less. Because the definitions of both the mole and the atomic mass unit are based on the same reference substance, 12 c, the molar mass of any substance is numerically equivalent to its atomic or formula weight in amu.per the amu definition, a single 12 c atom weighs 12 amu (its atomic mass is 12 amu). according to the definition of the mole, 12 g of 12 c contains 1 mole of 12 c atoms (its molar. Potassium bromide’ kbr contains 32.9% by mass of potassium. if 6.40 g of bromine reacts with 3.60 g of potassium, calculate the number of moles of potassium that combine with bromine to form kbr. answer: mass percentage of k = 32.9 ∴ mass percentage of br = 100 – 32.9 = 67.1 now 67.1 g of bromine combines with 32.9 g of potassium.
