| May 8, 2021 | education
The amount of a substance in chemistry is determined by the formula:
n = m / M,
m is the mass of the substance in grams;
M is the molar mass of the substance in grams / mol.
The molar mass of platinum is 195 g / mol and is taken from the periodic table.
n = 0.05 mol according to the condition of the task.
m = M * n = 195 * 0.05 = 9.75 g.
