How many grams are in a 6.94 mole sample of sodium hydroxide?
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).
How many grams of Ti are found in a 0.65 mole sample?
To determine the mass of Ti in a 0.65 mole sample, you need to know the molar mass of titanium. Titanium's molar mass is approximately 47.87 g/mol. Multiply the number of moles (0.65) by the molar mass (47.87 g/mol) to find the mass of titanium in the sample. So, 0.65 mol * 47.87 g/mol = approximately 31.1 grams of Ti in the sample.
How many grams of sodium are in a 1 mole sample of sodium?
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.
How many Sn atoms are there in a 86.0 gram sample of Sn?
86.0 grams Sn (1 mole Sn/118.7 grams)(6.022 X 1023/1 mole Sn)= 4.36 X 1023 atoms of tin=================
How much mass is in a 3.25-mole sample of NH4OH (molar mass 35.04gmol)?
To find the mass of a 3.25-mole sample of NH4OH, you can use the formula: mass = moles × molar mass. Therefore, mass = 3.25 moles × 35.04 g/mol = 113.88 grams. Thus, a 3.25-mole sample of NH4OH has a mass of 113.88 grams.
How many grams are in a mole of he?
4.003 grams
How many grams are in one mole of C5H12?
The molar mass of C5H12 is 72 grams/mole.
Which sample contains a mole of atoms?
A mole of atoms is defined as 6.022 x 10²³ atoms, which is Avogadro's number. Therefore, any sample containing this number of atoms, regardless of the element or compound, contains a mole of atoms. For example, a sample of 12 grams of carbon-12 (C-12) contains exactly one mole of carbon atoms. Similarly, a sample of any substance with a molar mass equal to its atomic or molecular weight in grams will also contain a mole of atoms when measured in that amount.
How many sodium ions can be found in 145g of NaCl?
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 =====================
What is the mass 1 mole of carbon?
