120 grams of calcium contain 2,994 moles.
120 g calcium is equal to 3 moles.

To find the mass of hydrogen produced from 120 moles of zinc reacting with hydrochloric acid, we first note the balanced chemical reaction: [ \text{Zn} + 2\text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2 ] From the reaction, 1 mole of zinc produces 1 mole of hydrogen gas. Therefore, 120 moles of zinc will produce 120 moles of hydrogen. The molar mass of hydrogen (H₂) is approximately 2 grams per mole, so the mass of hydrogen produced is: [ 120 , \text{moles} \times 2 , \text{g/mole} = 240 , \text{grams} ]
1 gram= 1000 mg. So 120 mg= 0.12 grams.
There are approximately 8 tablespoons in 120 grams.
120 g calcium is equal to 3 moles.
i think its 120 (40x3)

To find the number of moles in 120 grams of sodium, divide the given mass by the molar mass of sodium. The molar mass of sodium is approximately 23 grams per mole. Therefore, 120 grams of sodium is equal to 120/23 ≈ 5.22 moles of sodium.
To find the molarity, first calculate the number of moles of calcium nitrite using its molar mass. Then, divide the number of moles by the volume of the solution in liters (240 mL = 0.24 L) to get the molarity.
0.67 moles of C6H12O6
0,288 moles
120 ml of water weighs 120 grams
i think it equals .120 grams
120 grams = 4.233 ounces
