The atomic weight of magnesium is 24.31; therefore, the number of moles in 100 gm is 100/24.31 = 4.11, to the justified number of significant digits.
There are 2.47 moles of Mg atoms in 100 g of Mg. This is calculated by dividing the given mass by the molar mass of Mg (24.305 g/mol) to get the number of moles.
1 mole.
The molar mass of barium (Ba) is approximately 137.3 g/mol. So, the mass of 3 moles of barium would be 3 moles x 137.3 g/mol = 411.9 grams.
Sodium hydroxide is a strong base commonly used in various industries for pH adjustment and chemical processes. A 3M solution would mean it is a 3 mol/L concentration of sodium hydroxide dissolved in water. It is important to handle it with care due to its caustic nature.
To calculate the number of moles in 76 grams of NaCl, you need to divide the given mass by the molar mass of NaCl. The molar mass of NaCl is approximately 58.5 g/mol. So, 76 grams of NaCl is equal to 76 g / 58.5 g/mol ≈ 1.30 moles.
Molar mass of glucose (C6H12O6) = 180 g/mol. Number of moles of glucose = 16 g / 180 g/mol = 0.089 moles. Volume of solution = 300 ml = 0.3 L. Molarity = number of moles / volume of solution = 0.089 moles / 0.3 L ≈ 0.297 M.

There are 100 ml in 100 gm.
1 cup is 250 gm. -So 100 gm is about 2/5 of a cup.
100 grams = 3.52739619 ounces
A tablespoon is 15 gm, So 100 gm of butter is 6.6 tbsp
