To determine the number of molecules in 45 g of silver, you first need to calculate the number of moles of silver using its molar mass (107.87 g/mol). Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to molecules.
45/94.2 is 0.4777 moles
978 g calcium contain 24,4 moles.
29,0 g of calcium is equal to 0,723 moles.
67,4 g HCl is equivalent to 1,85 moles.
