The gram Atomic Mass of titanium is 47.867. Therefore, in a 0.65 mole sample, there will be 0.65 X 47.867) = 31 grams, to the justified number of significant digits.
The molar mass of an element corresponds to the atomic mass of the element (found on the periodic table). The atomic mass of Sodium-Na is 22.990 g, which is also the molar mass of Na. So for 1 mole of Na, there are 22.990 grams of Na. If we had 3 moles of Na, then we would simply multiply the molar mass by 3.
The molar mass of C5H12 is 72 grams/mole.
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ratio of isotopes equal to that in nature - has a mass of 12.0107 grams.
Depends on how much of the sample there is.
The molar mass of salt (NaCl) is 58.44 grams per mole. Therefore, there are 58.44 grams in 1 mole of salt.
The gram atomic mass of germanium is 72.6, to two significant digits. Therefore, in a 3.11 mole sample there will be (3.11)(72.6) = 226 grams, to the justified number of significant digits.
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams per mole. Therefore, a 6.94 mole sample of sodium hydroxide would contain approximately 278 grams (6.94 moles x 40 grams/mole).
The molar mass of an element corresponds to the atomic mass of the element (found on the periodic table). The atomic mass of Sodium-Na is 22.990 g, which is also the molar mass of Na. So for 1 mole of Na, there are 22.990 grams of Na. If we had 3 moles of Na, then we would simply multiply the molar mass by 3.
86.0 grams Sn (1 mole Sn/118.7 grams)(6.022 X 1023/1 mole Sn)= 4.36 X 1023 atoms of tin=================
4.003 grams
The molar mass of C5H12 is 72 grams/mole.
145 grams NaCl (1 mole NaCl/58.44 grams)(1 mole Na +/1 mole NaCl)(6.022 X 1023/1 mole Na +) = 1.49 X 1024 ions of sodium =====================
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ratio of isotopes equal to that in nature - has a mass of 12.0107 grams.
Depends on how much of the sample there is.
The answer is 165,23 grams.
25 grams / (17 grams/mole) x 6.022x1023 molecules/mole = 8.9x1023 molecules
The molar mass of salt (NaCl) is 58.44 grams per mole. Therefore, there are 58.44 grams in 1 mole of salt.
