How many gram does one mole of helium gas weighs?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.
How many moles are in 5.87 g Ni?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Nitrogen's atomic mass is 14.007 grams.
Which are true statements A There are 6.02 times 1023 particles in a moleB The mass of 1 mol is the same as the atomic mass in grams A mole weighs 6.02 times 1023 amu A mole is the atomic mass?
please someone help me with this
What is the mass of one mole of an element that has an atomic mass of 6.94?
This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)
Is the mass of 1 mole of oxygen and 1 mole of S same?
No, the (molar) mass (ie. the mass of one mole) is different by factor 2.004:Oxygen atom (O)15.999 g/mole O2,Oxygen molecule (elemental gas, O2) 31.998 g/mole O2Sulfur atom (S) 32.06 g/mole S,Sulfur molecule (bright yellow solid, S8) 256.48 g/mole S8,Sulfur molecule (S2) 64.12 g/mole S2 (there are more than 20 other allotropes)
Is the mass of 1 mole of O and 1mole of S same?
No; 1 mole of molcular oxygen (O2) is 31,998 g and 1 mole of sulfur (S) is 32,06 g.
One mole of Nacl is how many grams and how?
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.
Is 1 liter equal to 1 mole?
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.
What is the mass of 3.42 moles of NaOH?
3.42 moles NaOH (39.998 grams/1 mole NaOH) = 137 grams NaOH
How is the mass of 1 mole of an element determined?
It is the same as the element’s atomic mass, but in grams.
What mass of hydrogen contains the same number of atoms as 7.00g of nitrogen?
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 mass of 1 mole of an element (in grams) is the same as which quantity?
The atomic mass of the element in atomic mass units
What is the mass in grams for 3.011 X 10 23 atoms F?
1 mole of any element is its atomic weight (from the periodic table) in grams.1 mole of atoms of an element is 6.022 x 1023 atoms (Avogadro's number).1 mole F = 18.9984032g F1 mole F = 6.022 x 1023 atoms FConvert atoms of F to moles F.3.011 x 1023 atoms F x (1mole F/6.022 x 1023 atoms F) = 0.5000 mole FConvert moles F to g F.0.5000 mole F x (18.9984032g F/1mole F) = 9.499g Fe
How many grams of magnesium contain the same number of atoms as 16.2g of calcium?
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

How many grams in one mole of silicon?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Selenium's atomic mass is 78.96 grams.
