1 mol of an element is equal to it's atomic weight, but with grams instead of amu (or daltons) as the unit.
For example, with copper (Cu), 63.5 amu is its rough atomic weight, which means it weighs roughly 63.5g per mol.
Then we just need to divide through.
63.5 x 0.345 = 21.9g
To find the number of grams in 3.75 moles of KCl, you would first calculate the molar mass of KCl, which is approximately 74.55 g/mol. Then, you would multiply this molar mass by the number of moles (3.75 moles) to get the answer, which is 279.56 grams of KCl.
To determine the grams in 1.25 moles of a substance, you need to know the molar mass of the substance. By multiplying the number of moles by the molar mass, you can calculate the grams. Without specifying the substance, the answer cannot be determined.

To determine the number of moles of sulfur in 53.7 grams, you first need to calculate the molar mass of sulfur, which is approximately 32.06 g/mol. Then, divide the given mass by the molar mass to find the number of moles. In this case, 53.7 grams of sulfur is equivalent to about 1.68 moles.
To find the number of moles in 27.8 grams of water, you would first calculate the molar mass of water (18.015 g/mol). Then, divide the given mass by the molar mass to get the number of moles. In this case, 27.8 grams divided by 18.015 grams/mol is approximately 1.54 moles of water.
To find the number of moles of Na in 42 grams, we can use the molar mass of Na, which is approximately 23 grams/mol. First, calculate the number of moles by dividing the given mass by the molar mass: 42 grams / 23 grams/mol = 1.83 moles of Na.
