No; 1 mole of molcular oxygen (O2) is 31,998 g and 1 mole of sulfur (S) is 32,06 g.

Mole = Mass/RMM Ar for Na=23 & Ar for Cl = 35.5 Therefore 1mole = Mass / (35.5+23) 1 mole of NaCl is 58.5g Mole = Mass/RMM Ar for Na=23 & Ar for Cl = 35.5 Therefore 1mole = Mass / (35.5+23) 1 mole of NaCl is 58.5g But that can be misleading. NaCl does not form into molecules (and salts in general do not). If you dissolve 58.5g of NaCl into water, it will dissociate into ions, and there will be 2 moles of particles in solution: 1 mole of Na+ ions, and 1 mole of Cl- ions. Knowing that will be important for calculating various things, such as how many degrees the freezing point will be depressed, when you dissolve so much salt in so much water.
No. A liter is a volume measurement for fluids (liquids and gases). A mole is 6.022 x 1023 of anything. In gases at STP, 22.4L = 1mole.
The atomic mass of the element in atomic mass units
I assume you mean 40.59 grams of aluminum. 40.59 grams Al (1 mole Al/26.98 grams)(6.022 X 10^23/1 mole Al) = 9.05978 X 10^23 atoms in that mass aluminum 9.05978 X 10^23 atoms (1 mole Mg/6.022 X 10^23)(24.31 grams/1mole Mg) = 36.57 grams of magnesium
To convert grams per mole to atomic mass units (amu), you can use the conversion factor 1 gram per mole is equal to 1 amu. This means that the numerical value of the atomic mass in amu is the same as the molar mass in grams per mole.
39.95 because that is the molar mass of Argon
Let's see. 7.00 grams nitrogen (1 mole N/14.01 grams)(6.022 X 10^23/1 mole N) = 3.01 X 10^23 atoms of nitrogen 3.01 X 10^23 ( 1mole H/6.022 X 10^23)(1.008 grams/1 mole H) = 0.504 grams of hydrogen
the molar mass 1 mole = xxx grams based on the chemical formula Ex: CO2 ... the atomic mass of carbon is 12, and the atomic mass of oxygen is 16 but the molar mass = (1 x 12) + (2 x 16) because of the number of atoms of each in the formula. molar mass = 44. so 1 mole = 44 grams ... turn this fact into a conversion factor. 44g / 1mole is the conversion factor to convert moles of carbon dioxide into mass (grams). Each substance will have a different molar mass, so a different conversion factor.
The molar mass of Argon is 39.95g. Therefore 1 mole of Argon is 39.95g
The mass of 1 mole of an ionic compound is called the molar mass. It is typically expressed in grams per mole.
1 mole of silver contains Avogadro's number of silver atoms, while 1 mole of gold contains Avogadro's number of gold atoms. The molar mass of silver and gold can be used to determine the mass of each element in 1 mole. Both contain the same number of atoms per mole due to Avogadro's number.
