The atomic mass of the element platinum (Pt) is 195.08 amu. How many atoms of platinum are in 195.08 grams?(1 point) Responses 6.022×1023 atoms 6 point 0 2 2 times 10 to the 23th power atoms 1.951×1025 atoms 1 point 9 5 1 times 10 to the 25th power atoms 1.175×1026 atoms 1 point 1 7 5 times 10 to the 26th power atoms 3.087×1021 atoms
The molar mass of platinum is 195.08 g/mol, which means that 1 mole of platinum weighs 195.08 grams and contains 6.022 x 10^23 atoms.
To calculate the number of atoms in 195.08 grams of platinum, we need to divide the given mass by the molar mass:
Number of moles = 195.08 g / 195.08 g/mol = 1 mole
Therefore, there are 6.022 x 10^23 atoms of platinum in 195.08 grams.
Therefore, the answer is:
6.022×10^23 atoms
