13 multiplied by 169.87 (g/mol) = 2208.3g
Multiply moles by molecular mass of water (18), gives you 223.8g. Remember this formula: Number of moles = mass / molecular mass
mass = moles x Relative atomic mass So that's just 4.5 x 48 = 216g
2.000 moles of oxygen atoms weigh 32.00 g. 2.000 moles of oxygen molecules, on the other hand, weigh 64.00 g.
As the molar mass of water is 18 g/mol (1*2 H + 16 O) 10 moles*18 g/mole=180 grams.
They weigh the same.
5.0 mol Li * 6.941 g/mol Li = 34.705 = 35 g Lithium
(63.29oz.)
The mass is 27,576 g.
1 mole weighs 183.54 g. So, 3.95 moles will weigh 724.983 g
