1 mole weighs 183.54 g.
So, 3.95 moles will weigh 724.983 g
1 mole is equal to 18 grams of H2O, so 60 grams is 3.33 moles.
To find the number of moles in 500 grams of radium (Ra), you need to divide the given mass by the molar mass of radium. The molar mass of radium is approximately 226 grams/mol, so 500 grams of radium is equal to 500 grams / 226 grams/mol ≈ 2.21 moles of radium.
The molar mass of sodium hydrogen carbonate is 84 grams per mole, therefore 0.5 moles of it weighs 42 grams.
To find the grams in 6.20 moles of NaCl, you need to multiply the number of moles by the molar mass of NaCl. The molar mass of NaCl is 58.44 g/mol. Therefore, 6.20 moles of NaCl is equal to 362.49 grams.
To find the number of moles in 57 grams of Xenon, divide the given mass (in grams) by the molar mass of Xenon. The molar mass of Xenon is 131.3 grams/mol. Therefore, 57 grams of Xenon is equal to 0.434 moles (57/131.3).
0.377 grams of Kr is equal to 0,0045 moles.
124 grams of ethane is equal to 4,124 moles.
370 grams of mercury is equal to 1,844 moles.
1,99 grams of aluminum is equal to 0,0737 moles.
15 grams of nitrogen are equal to 1,071 moles.
6,5 grams of sulfur S are equal to 0,203 moles.
