How many mols are contained in 6.05g of carbon?
For this problem, the atomic mass is required. Take the mass in grams and divide it by the atomic mass. Then multiply it by Avogadro's constant, 6.02 × 1023..06 grams C / (12.0 grams) × (6.02 × 1023 atoms) = 3.01 × 1021 atoms
How many grams of NaOH are in 1.25 mol NaOH?
5.25 grams Ba(OH)2 (1mol Ba(OH)2/171.316 grams Ba(OH)2 ) = 0.0306 moles Ba(OH)2
What is the mass in grams of 3.50mol LiBr?
step 1: calculate the molar mass of one molecule LiBr by adding together their amu (atomic mass units) step 2: 3.50 mol * ( molecular mass LiBr / 1 mol LiBr ) = grams LiBr amu on your periodic table is grams when you have one mol of that substance
What is the mass of 5 moles H2?
The molar mass of H2 is 2 g/mol. To find the mass of 5 moles of H2, you would multiply the molar mass by the number of moles: 2 g/mol * 5 mol = 10 grams.

What is the mass in grams of 6.25 mol of copper II nitrate?
To find the mass in grams of 6.25 mol of copper(II) nitrate (Cu(NO3)2), you need to first calculate the molar mass of the compound using the periodic table. The molar mass of Cu(NO3)2 is 187.56 g/mol. Multiply the molar mass by the number of moles to find the mass: 6.25 mol * 187.56 g/mol = 1172.25 grams.
How do you convert 2lb mol of C3H8 to gram?
To convert 2 lb mol of C3H8 to grams, you need to first determine the molar mass of C3H8 (propane) which is approximately 44.1 g/mol. Then, you can multiply the number of moles (2 lb mol) by the molar mass to get the mass in grams. So, 2 lb mol of C3H8 is equal to 2 lb mol * 44.1 g/mol = 88.2 g.
