A mole weighs 58 grams
72.8grams
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
The molar mass of potassium (K) is approximately 39.1 g/mol. Using this molar mass, we can calculate the weight of 35.1 moles of potassium by multiplying the molar mass by the number of moles. Therefore, 35.1 moles of potassium would weigh approximately 1371.41 grams.
mass = moles x Relative atomic mass So that's just 4.5 x 48 = 216g
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
0.723 moles of ZnO2 would weigh approximately 141.6 grams. This is calculated by multiplying the number of moles (0.723) by the molar mass of ZnO2 (196.44 g/mol).
2.000 moles of oxygen atoms weigh 32.00 g. 2.000 moles of oxygen molecules, on the other hand, weigh 64.00 g.
The mass is 27,576 g.
The molar mass of iron is 55.85 g/mol. To find the weight of 7.4 moles of iron, you would multiply the number of moles by the molar mass. Therefore, 7.4 moles of iron would weigh 7.4 moles * 55.85 g/mol = 411.49 grams.
